Elitech PG-30 Red Digital HVAC Gauge High Pressure Gauge

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. Feature Unit conversion between MPa, kPa, bar, psi, kg/m2,cmHg. Pressure range is -14.5~800psi (-0.1~5.5MPa), accuracy: ¡À0.5%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. 2 X Range Overload Protection Resolve the problem occurred on traditional pressure gauge£ºeasy damaged by overload pressure Preform 2 X range overload protection Record MAX/MIN value automatically Long Battery Life Adopts low-consumption MCU Built-in high-capacity button cell Up to 6 months of battery life and avoid replacing it frequently. Auto-off Function Press ¡ø/SET and ¨‹/ZERO button at the same time then the auto-off mode will be started or canceled. When it begins, the pressure gauge will be auto-off within 20 minutes, which will extend the standby time.
