Automotive negative pressure measurement
Equipped with a black conical head for connecting to the car, it can measure the negative pressure value of the crankcase of the car.
Measurement of negative pressure, positive pressure and differential pressure
The single channel of the pressure gauge can quickly measure the current detection pressure value, while the dual channel can simultaneously measure the pressure difference between the two detection ports. Instant overpressure function. If there is no work for 10 minutes, the pressure gauge will automatically shut down to avoid wasting electricity.
11 Units of Measurement
Psi, kPa, Kgfcm2, ozin2, Bar, mbar, inHg, mmHg, inH2O, ftH2O and cmH2O. The large display has an LCD backlight that can show clear data even in dark or low light conditions.
