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.

Key Feature：

• 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) 

• 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.

• 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

• 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.
