PG-30PRO Digital Pressure Gauge

PG-30Pro is a digital pressure gauge that measures system pressure in real time. It features a big artistic screen and batteries with 1-year service life. The gauge has a backlight, auto off, low battery indication, overpressure alarm, and other functions. It is designed for use in a piping system, refrigerated system and other applications.


  1. Stable and Reliable Sensor: temperature-compensated pressure sensor, temperature drift not exceeding ±0.04%FS/℃

  2. LCD Screen & Blue Backlight Display: Partition display for different measurements, direct readings for all measurements.

  3. Various Refrigerants Options: Built-in 87 types of normal refrigerants PT comparison table for your convenience

  4. Zero Function: If a deviation occurs at zero point, use ZERO button to zero out and correct the system.

  5. Two overload warning indications: The screen displays ALARM or if the overload is too high, the ALARM & backlight will flash simultaneously.
