Absolute Pressure And Gauge Pressure Meters, Suitable For Gases And Liquids

The true absolute pressure of the medium is measured with the absolute vacuum as the zero point reference, and it is not affected by the changes in local atmospheric pressure. 

Applicable scenarios (must use absolute pressure conditions)
Vacuum units, negative pressure pumping, vacuum pump systems
Laboratories, vacuum monitoring of tanks
Meteorology,  semiconductor vacuum processes
Low pressure, negative pressure conditions, cannot be replaced by gauge pressure
Precise measurement in high altitudes with large fluctuations in atmospheric pressure
Absolute pressure and gauge pressure gauges, suitable for gases and liquids 

When measuring vacuum, negative pressure, and avoiding interference from atmospheric pressure, choose an absolute pressure transmitter.
