Read Refrigerant Pressure, Temperature and Vacuum on One Digital Gauge
The L202 digital refrigerant gauge uses a high-precision pressure sensor and a built-in database of 90 refrigerants to show pressure and the matching refrigerant temperature in real time, for installing and servicing automotive and refrigeration systems.
- 3 Working Modes
- Pressure Leak Test
- Adjustable Brightness
- Hanging Hook
Key Features
-
Refrigerant Measurement Mode
For charging a system with refrigerant, with real-time pressure, temperature and refrigerant type on screen.
-
Vacuum Measurement Mode
For evacuating a system, showing the current vacuum pressure and the percentage of vacuum.
-
Leak Detection Mode
Checks a system for pressure leaks, showing the current pressure, leak pressure and work time.
-
Rotary Valve Control
A rotary switch with a 90-degree limit turns the valve between ON and OFF.
-
Adjustable Screen Brightness
Short-press the power key to change the display brightness.
-

How to Use
- Attach the hoseConnect the hose securely to the low-pressure pipe.
- Connect the vacuum pumpConnect the vacuum machine to the right port and make sure it is sealed.
- Open the low-pressure valveCarefully open the low-pressure valve, using the right tools to avoid damage.
- EvacuateRun the vacuum pump until it reaches a complete vacuum.
- Connect the refrigerantConnect the service hose tightly to the refrigerant canister.
- Run the A/CStart the engine and set the air conditioner to maximum so the refrigerant circulates.
- Check and adjustConfirm the gauge is in the correct mode and adjust as needed.
Good to Know
Care
- Keep the gauge and screen clean; wash the case and connectors with a slightly alkaline detergent or soapy water.
- Check the gauge regularly to confirm its accuracy.
- Handle gently to prevent shocks and falls.
- Close all knobs after use.
- Plug the connectors when not in use, and clean or replace refrigerant hoses regularly to remove dirt from the valves.
