Digital high pressure gauge PG-30Pro digital high-pressure gauge that measures system pressure in real-time. It is designed for use in the piping system, refrigerated system and other applications.

Stable and Reliable Sensor

• Use temperature-compensated pressure sensor

• Six different measuring units to choose: MPa, kPa, bar, psi, kg/cm², cmHg

• A wide range of measurement: -0.100 ~ 5.515MPa (-14.5-800 psi) 

Two Overload Indication

• It displays “ALARM” on the right top of the screen when overload is higher than 800 psi.

• Backlight flashes and screen displays "ALARM" when the overload is above 1001 psi.

LCD Screen& Blue Backlight Display

• The air pressure gauge's digital backlight display allows you to readout easily even in the night.

• Partition display for different measurements, direct readings for all measurements.

• Adjustable backlight off time: 3s,4s,5s,10s,15s asset in case of no operation.

• Selectable Auto-off time: 10min (default), 20min,30min,40min

Various Refrigerants Options and Zero Function

• PT tables list 87 types of normal refrigerants

• Switch Refrigerants: on the home page, press and release SET or ZERO key to scroll through refrigerant types and related value.

• If deviation occurs at zero points, use the ZERO key to zero out and correct the system.

• In MAX/MIN page, press and hold the ZERO key to clear the MAX/MIN value.

• On the homepage, press and hold the ZERO key to clear current value; press and hold it again to recover the value.

• Note: Do not ZERO during measurement.

•
