High-resolution Hot Wire Anemometer for Measuring Air Velocity and Temperature

various units selectable / hot wire telescopic probe extendable up to 1 meter / USB data cable and software for online data transmission

The PCE-423 is a Hot Wire Anemometer for measuring temperature, volume flow and flow velocity. The Hot Wire Anemometer, consisting of a display unit and a heat wire probe, enables a fast and precise measurement, especially of the low air speeds. The measuring range of the high-resolution anemometer ranges from the smallest flow velocities up to 25 m / s. There, different units (m / s, knots, km / h, mph, ft / min) can be selected for the flow velocity. For volume flow measurements, a distinction can be made between CFM and CMM.

Due to the combination of a telescopic rod and a thin measuring head, a Hot Wire Anemometer from PCE can be used in the places, where there is little measuring space available or where the measuring point is difficult to reach for the examiner. The telescopic probe of the Hot Wire Anemometer can be extended to a length of up to one meter and its measuring head has a diameter of ten millimetres.

The user of the device is able to read out the results optimally even in a dark environment. It is possible, because the large, illuminated LC display on the Hot Wire Anemometer facilitates the measurement of the air flow in low light conditions. A Hot Wire Anemometer, like the PCE-423, stores maximum and minimum values that can be retrieved on the display later. So that the last measurement results could be viewed again, the Hot Wire Anemometer has a Data-Hold function. In order to save the battery when the device is not in use, the Hot Wire Anemometer has an integrated Auto-Power-Off function, which ensures that the meter shuts off by itself after five minutes.

After entering the channel cross-section, a Hot Wire Anemometer, besides measuring the temperature and flow velocity, also allows for the determination of the volume flow in channels.

To log the measured values, the flowmeter is equipped with a USB interface. As a result, with the help of the supplied software, the data can be transferred to a PC and evaluated.


Hot Wire Anemometers are used in the air conditioning, heating and ventilation technologies. Small changes in the air velocity are often not directly visible, but can still have a significant impact on indoor air quality within enclosed buildings and rooms. Hot-Wire Anemometer PCE-423 applicationThat is why, regular monitoring of this influence is of a big importance. The Hot Wire Anemometer from PCE Instruments detects the lowest air speeds from 0.1 m / s at a resolution of 0.01 m / s and is therefore particularly suitable for the control of the ventilation and air conditioning systems. Even low air velocities near not-airtight windows and doors can be detected by a Hot Wire Anemometer of this kind very precisely. The Hot Wire Anemometer is robust, handy and easy to use. For installers, service technicians and building consultants, a Hot Wire Anemometer such as the PCE one is indispensable. Accessories and service In addition, PCE Instruments offers the ISO Calibration Certificate CAL-A for air flow meters to comply with DIN ISO 9000. The calibration certificate confirms the metrological characteristics of the Hot Wire Anemometer as well as the traceability of the measurement results to the national standards. Calibration certificates are issued specifically for the customer, the annual recalibration can also be carried out by PCE Instruments.
