PG-30 Red & Blue Digital Pressure Gauges

PG-30 digital pressure gauge can test pressure and corresponding evaporation temperature, with backlight, manual calibration, automatic shutdown, units conversion, low power alarm, refrigerant types selection and other functions. Battery life up to six months, used for refrigerant and maintenance, pressure vessels, pressure monitoring.

Key Features:

Unit conversion between MPa, kPa, bar, psi, kg/m2,cmHg. High side: -14.5~800psi (-0.1~5.5MPa), Low side: -14.5~500psi (-0.1~3.4MPa), accuracy: ±0.5%FS, resolution: 0.5psi.

Automatically perform pressure/temperature calculations for up to 91 different refrigerants, including R134A, R410A, and R22 refrigerants and etc.

The air pressure gauge's digital backlight display provides clear results even in the night. The 4-digit LCD display allows for easy point-of-reference pressure readings.

Powered by a CR2450 battery and works around 6 months. The backlight automatically shut down in 6 seconds, power-saving and longer using time.

Displays screen alarm indication when over range; adjustable temperature unit: Celsius or Fahrenheit; rugged housing with registration for reliable service.
