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.
- 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.
- Operating Temperature and Humidity: 10°C ~60°C; 35% ~ 85%RH
- Resolution: Pressure: 0.001MPa; Temperature 0.1°C
- Accuracy: Pressure : ±5%FS (22°C ~ 28°C); Temperature： ±1°C
- Battery Life: Six Months
- Power supply: 3V CR2450 button battery
- Sampling Period: 1.2s
- Battery Indicator: displays 'LOB' at low battery
- Display: 30mm*17mm LCD/green back-light, auto-off after 6s
- Measurement Units: MPa, kPa, bar, psi, kgf/cm2, mmHg
- Out-of-Range Alarm: pressure: FULL
- Wear safety goggles when working with refrigerants. Refrigerants can cause eye injury.
- Disconnect hoses using extreme caution, Pressurized refrigerant may be present in hoses. Point hoses away from you and anyone nearby.
- On/Off: In power-off mode, press and release Light/Power button to turn on the gauge and display current pressure. Press and hold Light/Power for 3 seconds to turn it off. It will be auto-off after 15 minutes of inactivity.
- Backlight: In power-on mode, press and release Light/Power button to turn on backlight. It will be auto-off after 6 seconds of inactivity.
- Max and Min Memory and Clear: Press and release Up/Set or Down/Zero button to display Max or Min values. Press and hold Up/Set or Down/Zero button for 3 seconds to clear the displayed Max or Min.
- Zero: Press and hold Down/Zero for 3 seconds to zero. It will display 18.104.22.168 and then 0.000 after 3 seconds. Press and hold the button again for 3 seconds to display current relative pressure.
- Auto-Off: Press and hold Up/Set button for 3 seconds to enter refrigerant types selection. Press Light/Power in 3 seconds, °C will flash to indicate temperature units shift. Press Light/Power in 3 seconds, MPa will flash to indicate pressure units shift. Press Light/Power in 3 seconds to exit. Use Up/Set or Down/Zero for selecting the specific refrigerant type or temperature/pressure unit.
