The differential pressure gauge is a pressure gauge for simple, fast and precise pressure measurement of air and non-explosive gases. Due to its design, the differential pressure gauge is suitable for the application in the measuring range from -138 to +138 mbar and, by means of a special software, for the complete display of the measurement results.
The differential pressure gauge from PCE Instruments measures differential pressure as well as relative pressure and can be switched to different units. Eleven pressure gauge units are adjustable: in H2O, psi, mbar, kPa, inHg, mmHg, ozin2, ftH2O, cmH2O, kgcm² and bar. At the resolution of 0.1 mbar, the differential pressure gauge achieves an accuracy of 0.3%.
The differential pressure gauge is delivered with four 30-centimeter-long silicone connection hoses that can be attached to the meter. Thus, the manufacturer enables the user to immediately use the differential pressure gauge. Many practical functions make the handy and mobile pressure gauge versatile and usable everywhere. The large, backlit display of the differential pressure gauge makes it possible to read-out the measurement results optimally. Depending on your needs, the backlight can be switched on and off. In this way, the user can quickly view all the data, even in the low light conditions. The dual LCD also allows a direct comparison of minimum, maximum and average values with the current measurement results. In order to be able to read-out the last measurement results again, the differential pressure gauge from PCE Instruments has a practical Data-Hold function.
A battery symbol allows the user to keep an eye on the battery status of the differential pressure gauge at all times. To protect the battery, the manufacturer has equipped the meter with an auto-power-off function. When not in use, the differential pressure gauge switches off automatically after a short time. However, this function can be turned off when needed. To ensure that the meter can also be used for long-term measurements, it is specifically equipped with a power supply. Even a zero-point adjustment is possible with the differential pressure gauge. Thus, the device can, for example, be zeroed against atmosphere, or even a measurement with offset values is possible.
The supplied software and a USB cable make a simple and complete documentation of the data possible. Pressure fluctuations, for example, can be transmitted to the computer every second due to the included software and can be displayed in a tabular and graphical form.

The differential pressure gauge is particularly suitable for the application in the measuring range from -138 to +138 mbar. Manometers, like this PCE Instruments gauge, are preferred in industry, research and air conditioning to determine differential pressures of air and gases. The handy and robust design of the plastic housing and the versatile functions make the differential pressure gauge flexibly applicable and the ideal companion for technicians, installers and experts, for example, in ventilation and heating technology.

As an accessory to the differential pressure gauge, PCE Instruments offers the PVC hose for pressure gauges. With a length of two meters and an inside diameter of 3.5 millimetres, the hose can be individually tailored and adapted to the personal requirements.
In addition to the differential pressure gauge, PCE Instruments offers an ISO calibration certificate for the PCE-P series to comply with DIN ISO 9000. Calibration certificates are issued specifically for customers, the annual recalibration can also be performed via PCE Instruments.
