With the Pyrometer PCE-IR 50, surface temperatures can measured quickly and easily. The measuring range of the pyrometer is 0 … 500 °C / 32 … 932 °F. The measured temperature is output as a 4 … 20-mA standard signal which means that the pyrometer can be easily integrated into different monitoring systems, including those in different production processes or food storage as well as the monitoring of electronic systems.
The pyrometer is suitable for private and industrial use because of its price-performance ratio. An infrared pyrometer is a contactless measuring device. The bright laser dots from infrared instruments are clearly visible and provide easier temperature measurement from a distance.
With the PCE-890U-ICA Pyrometer, measurements of surface temperatures can be carried out quickly and easily. Since the pyrometer uses infrared radiation for temperature measurement, no direct contact with the measuring object is required.

The PCE-JR-911 Pyrometer with Thermometer is a versatile tool in that it can measure the temperature of objects without contact and readings can be stored in memory and transferred to a computer by way of its RS-232 interface and software. This Pyrometer comes complete with a Thermometer, allowing the user to program specific time intervals for taking measurements, such as over an entire week.
With the Pyrometer you get a measuring device with which you can perform a wide range of measuring tasks. On the one hand, you can directly measure and read the temperature of bodies without contact, on the other hand you can also save the measured values internally in the data logger and transfer them to a PC or laptop via the RS-232 interface.
A pyrometer is often called a laser thermometer, non-contact thermometer, infrared (IR) thermometer or IR temperature gun. A pyrometer uses infrared radiation, also known as thermal radiation, to indirectly measure surface temperature without contact. William Chandler Roberts-Austen was credited with the invention of the radiation thermometer. Any object with a temperature above 0 degrees Kelvin (K) emits radiation. A pyrometer solely measures the temperature of a visible surface. Therefore, a pyrometer cannot take measurements through glass. If the object being measured is colder than the pyrometer, the radiation flow is negative. To calculate the temperature, the pyrometer sends thermal radiation to the measured object to correct the negative flow.
A pyrometer offers many advantages. Measurement results can be obtained very quickly, from 10 µ to 1 second depending on the device. A pyrometer also elminates errors due to poor thermal contact. There is little wear or tear on a pyrometer, even on portable handheld units. High voltage, electromagnetic fields and corrosive materials do not affect the measurement process. Measurements taken with a pyrometer do not cause damage to sensitive objects such as plastic films or paper products. Another important advantage is that, because measurements can be taken without contact, a pyrometer is a much safer tool for use in high-temperature situations.
The ideal conditions to measure wavelength using a pyrometer depend on the material and its temperature. For the best readings at room temperature, wavelengths in the middle infrared range (MIR) are recommended. Thermal sensors inside the pyrometer, such as pyroelectric detectors, are used for this purpose.
Temperatures from approximately 350 °C (662 °F) can be determined in the near-infrared range (NIR) with infrared photodiodes, using a pyrometer. In this way, for instance, a germanium photodiode can have a lower receiving wavelength of approximately 1.9 µm. Temperatures from approximately 700 °C (1292 °F) in the visible spectral range can be measured with photodiodes. The pyrometers' receiving wavelength range for high temperatures are often determined by photoreceptors. For instance, the smallest receiving wavelength of silicon photodiodes is approx. 1.1 µm. An object with a temperature of 3000 K is at its maximum radiation, so with this you can measure temperatures from approximately 700 °C (1292 °F).
As discussed, the main advantage that a pyrometer possesses, in comparison to a regular contact thermometer, is that it provides non-contact measurement using emissivity. This means that within just a few seconds it is possible to determine the temperature in parts of machines, engines or systems that cannot be accessed easily without shutting down. In fact, because a pyrometer measures the emission coming from the surface of the material or object (as all objects emit energy and electromagnetic waves depending on their temperature), and since the energy depends on the temperature of the object to be measured, the temperature of the object's surface can be measured without immediate proximity and direct contact. Due to the installed software and laser sight, the pyrometer determines the coefficient of the emission of the object to be measured and provides a precise reading of the surface temperature in the exact target area.
Thus, a pyrometer is an ideal solution for monitoring heating, ventilation and air conditioning (HVAC) systems, parts and components. A pyrometer can be used for regular monitoring of HVAC systems as well as for troubleshooting and searching for the cause of an unidentified malfunction. The condition of an HVAC system plays an important role in any company, factory, warehouse, school or home. A pyrometer can be used to examine air ducts, pipes and walls. HVAC system maintenance is a challenging task, since not all the elements of the HVAC system are open to immediately access and inspect. That is why in HVAC system testing, adjusting and balancing (TAB), application of direct contact measuring devices is not always appropriate or easy. Often difficulties result not only from obstacles creating limited access to key measuring points within the HVAC system, but also from potential risks and dangers for the HVAC technician, for example, when the temperature of an HVAC system component becomes too hot for measurement to be carried out safely by contact.
A pyrometer enables HVAC inspection professionals to carry out necessary HVAC system tests and examinations on site, without using ladders or too much other auxiliary equipment, making inspection of the condition of the ventilation ducts, air conditioning vents, heating elements cooling pipes and the like simpler.
Most pyrometer devices are small in size, which makes transportation and handling absolutely problem-free. Plus, the accuracy and measurement results from most pyrometer products are impressive. A pyrometer can help to save a lot of time, effort and cost arising from unplanned shutdowns of equipment, machinery and systems. Non-contact measurements with the help of a pyrometer are carried out in real time and, when using devices with preset limits, it is easy to detect when operating conditions exceed permissible limits (as a rule, the pyrometer emits a sound or flashes a colored light as an audible or visual alarm warning signal).
Another area where pyrometer devices are implemented is in the field of medicine. For example, patients suspected of having highly contagious health conditions can be quarantined and have their body temperatures measured with a high degree of accuracy using special pyrometer technology.
A pyrometer is used to measure the surface temperature of an object without touching 
the object's surface. In practice, the object for which the surface temperature is to be measured can be anything from a rubber tire to a furnace heating element. This versatility makes a pyrometer an incredibly useful tool for inspection professionals in many diverse industries. However, to ensure accurate measuring results, the specifications of a pyrometer must align with the requirements of the application.
How do you determine what pyrometer is best suited to your application? The following text is designed to help you make an informed purchasing decision.
Key Questions to Ask Yourself When Choosing a Pyrometer for Infrared Temperature Measurement
Following is a more detailed analysis of criteria to keep in mind when selecting a pyrometer.
The answer to this question largely depends on the intended application. If you want to use the pyrometer to sporadically collect readings for quality assurance, a portable pyrometer should be used. If you want to measure continuously and use the readings for process control, it will be better to use a stationary pyrometer. A stationary pyrometer should be equipped with an interface to transfer readings to a process control system or controller. The transfer can be analog or digital.
A pyrometer can have its disadvantages. One such disadvantage is the need to know the 
required emissivity. The emissivity of a material is the relative ability of its surface to emit or absorb energy by radiation. Emissivity not only depends on the kind of material, but also on the anticipated surface temperature and the wavelength (µm) of the pyrometer. Another disadvantage is that the emissivities of metals vary widely, making accurate measurement difficult. For example, at 25 °C (77 °F) highly oxidized copper has an emissivity of 0.78, but at 527 °C (980.6 °F) the same highly oxidized copper has an emissivity of 0.91, while polished copper has an emissivity of 0.012 at 327 °C (620.6 °F). A table of approximate emissivity values for common materials can be viewed here. Emissivity values for the pyrometer Warning: The accuracy of the values shown in the table cannot be guaranteed, because emissivity is dependent on several variables (surface texture, color, temperature at time of measurement, etc.).
Whereas most glass, ceramic, plastic, wood and organic materials have very high emissivities (about 0.95) within the middle infrared range (MIR) and far infrared range (FIR), blank metals have much lower emissivities within the MIR and near infrared range (NIR) -- e.g., polished gold within the MIR has an emissivity of approximately 0.02. However, when metal is anodized (like aluminum) or highly oxidized, it will have a higher emissivity of about 0.9 within the MIR. When it comes to painted metals, the higher emissivity of the paint will be significant to the temperature measurement. The intensity and the emission maximum depend on the temperature.
Many pyrometer devices have a feature to adjust the emissivity. Often the emissivity is adjusted using a rotary knob with a range of 0 ... 1. Some pyrometer devices have an additional measuring input for a contact temperature sensor (or thermocouple). If you want the pyrometer calibrated for an unknown material to determine the emissivity, the temperature can be measured with this additional sensor. The setting for the emissivity in the pyrometer will be adjusted until the non-contact measurement produces the same measurement result as the measurement with the contact sensor.
Every pyrometer has a lens with a certain distance-to-target or distance-to-spot (D/S) ratio. Specifications like 2:1, 10:1 or 20:1 are very common for low-priced pyrometer devices. When looking at high-quality pyrometer devices, the specifications can be up to 75:1. These values also can be expressed as x:y. This means that the measuring spot has a diameter of y when the distance to a surface is x. For example, if a pyrometer has a distance-to-target ratio of 20:1, you can stand 20 centimeters or 20 inches away from your target and measure the temperature of a one-centimeter or one-inch circle. This is similar to the cone of light emitted by a flashlight. If you approach a wall very closely with a flashlight, the cone of light will be smaller than when you are farther away from the wall. More advanced pyrometers can reduce or increase the size of this measuring spot to meet the size requirements of the application.
Each pyrometer will have its own accuracy specifications that are dependent upon the temperature range being measured. Typically a higher accuracy measuring instrument will come with a higher price tag, so it is important to consider practicality as well as precision.
In addition to emissivity, influencing factors such as the surface thickness, geometry (even, concave, convex), finish (polished, rough, oxidized, sand-blasted) and transmissivity (thin plastic films) can affect results, as can the measurement angle and spectral range. Thus, when taking comparative temperature measurements with a pyrometer, it is vital to establish a control to minimize the effects of as many variables as possible to capture the most accurate readings.
Some pyrometer products save temperature readings to an internal memory or SD card memory. The size of the memory can be presented as a number of GB or as a maximum number of readings stored. This memory usually allows for the temperature measurement data to be downloaded to a PC using a USB port, RS-232 interface or SD card reader. In most cases, a pyrometer with temperature data recording capabilities is equipped with a USB connection. In some cases, special PC software is required to transfer the measurement data.
This is another important point to keep in mind. Find out how long the supplier has been in business. The longer the company's tenure, the more likely it is that you will be able to order spare parts a few years down the road after buying your pyrometer. PCE Instruments has been in business since 1999. (For more details, please visit the About Us / Corporate History section of our website.) Also find out what kind of technical support will be available to you. Call PCE Instruments, talk to the technical support team prior to purchasing and see for yourself the level of service provided.
Often more is involved in the budget than just the cost of the pyrometer. Calibration costs are common expenses that can occur when using a pyrometer. For instance, if you need to meet the requirements of an ISO quality standard, a regular calibration interval needs to be adhered to. ISO calibration costs can occur at the time of purchase and reoccur on an annual or even semi-annual basis, depending on your accuracy needs and usage of the IR thermometer. It is also possible that recalibration becomes necessary later on, due to the drift pyrometers and their sensors can experience over time. Consumables like (rechargeable) batteries should be included in your calculations as well.
