Elitech PG-30 Blue Digital Low Pressure Gauge for HVAC Refrigerant with Backlight -14.5~500 PSI 1/8” NPT
- ...ates the pressure difference between the initial test pressure and the second test pressure to determine if the refrigerant is leaking. Pressure leak measurement, leak time and speed record. Using a digital manifold gauge set can make your job easier..
- 6.【Refrigerant Gauges with Visual Window and LCD Display】The charging status of refrigerant can be directly observed through the refrigeration gauges window, which makes the operation more convenient. 7.5CM×4CM display screen, support LCD backlight, convenient lighting operation, the displayed data is clearer and easier to read..
- 7.【Note】The digital HVAC gauges will read random numbers when it is powered on. Correct steps: 1. Turn on, then close the two valves, press the “ZERO” key to clear the reading. 2. Then connect the three-color hoses, then open the valve, and use it normally. Please make sure that the refrigerant hose is properly connected. Poor connection may cause refrigerant leakage. The maximum working pressure of the standard hose is 600 PSI ( 4.13 Mpa, 41.3 bar). The ultimate pressure is 3000 PSI..
