Differential pressure gauge ( digital pressure gauge ) is widely used to measure fan and blower pressures , filter resistance , air velocity, furnace pressure , orifice differential pressure, air bubbles and liquid water pressure amplifier or hydraulic systems , but also for gas combustion air ratio control and automatic control valves , as well as the health care equipment monitoring blood pressure and respiration . 

Technical Parameters:

 Ambient temperature : -70 ~ 60 °C
 Rated Pressure : -68 ~ 103KPa
 Overvoltage : about 172KPa overvoltage when the rubber stopper has been rushed to open .
 Process connection : high and low pressure holes are 1/ 8 " threaded spinal canal , two ( side and back of a group )
 Housing material : die cast aluminum , aluminum and chrome body parts after 168 hours salt bath test , the final coating of dark gray exterior .
 Accuracy: at 21 °C is ± 2% FS (- 125PA; 250PA type is 2%,-60PA, type 2% )
