Elitech PG-30 Blue Digital Low Pressure Gauge for HVAC with Backlight -14.5~500 PSI

  • Unit conversion between MPa, kPa, bar, psi, kg/cm², cmHg. Pressure range is -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 CR2450 battery and works around 6 months. The backlight automatically shutdown 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. 

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, it is used for refrigerant and maintenance, pressure vessels, pressure monitoring.

2 X Range Overload Protection
  • Resolve the problem occurred on traditional pressure gauge:easy damaged by overload pressure
  • Perform 2 X range overload protection
  • Record MAX/MIN value automatically
Long Battery Life
  • Adopt low-consumption MCU
  • Built-in high-capacity button cell
  • Up to 6 months battery life and avoid replacing it frequently.
Auto-off Function
  • Press /SET and /ZERO button at the same time then the auto-off mode will be started or cancelled. When it begins, pressure gauge will be auto-off within 15 minutes, which will extend the standby time.
