DIFFERENTIAL MANOMETER Digital differential pressure gauge - pressure gauge GM510 by Benetech. Widely used in the automotive industry in the measurement of back pressure or differential pressure of DPF filters, It can also be used to measure the pressure of fans, air pressure, and monitor the gas content in the air during the combustion process. It has the ability to show results in up to 11 units! Selection: bar, mbar, kPa, kgf/cm², mmHg, cmH2O, Ozf/in², psi, inHg, inH2O, ftH2O. This device features features such as the ability to save data, calibration, auto-off function (which increases battery life), and the ability to connect to a computer via USB for reading and exporting data. The measurement range in bar is 0 - 0.100 - detailed specification below.
