Elitech PG-30Pro Blue Digital AC Pressure Gauge -14.5~500 PSI

Key Feature: Stable and Reliable Sensor: temperature-compensated pressure sensor, temperature drift not exceeding ¡À0.04%FS/¡æ LCD Screen & Blue Backlight Display: Partition display for different measurements, direct readings for all measurements. Various Refrigerants Options: Built-in 87 types of normal refrigerants PT comparison table for your convenience. Zero Function: If a deviation occurs at zero points, use ZERO button to zero out and correct the system. Two overload warning indications: The screen displays ALARM or if the overload is too high, the ALARM & backlight will flash simultaneously. 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.
