Read Both Sides of an A/C System: Pressure and Temperature at Once
The L302 digital manifold gauge shows low- and high-side pressure and temperature together and gives the matching refrigerant temperature for the measured pressure from 90 built-in refrigerants. Switch between refrigerant, vacuum and leak-test modes for installation and service work.
- Dual Pressure + Dual Temperature
- 90 Refrigerants (NIST Data)
- 3 Working Modes
- ±0.5% Accuracy
- Adjustable Brightness
Key Features
-
Dual Pressure Readings
Measures the low-pressure and high-pressure lines at the same time; the blue arrow marks low pressure and the red arrow high pressure.
-
Dual Temperature Readings
Shows the temperature of both lines alongside their pressures.
-
Three Working Modes
Refrigerant pressure, vacuum percentage and leak detection.
-
Built-In Refrigerant Database
Pressure-temperature data for 90 refrigerants following US NIST standards, including R410A.
-
Refrigerant and Vacuum Pressure
A high-precision pressure sensor reads both refrigerant pressure and vacuum pressure.
-
Readable Display and Foldable Hook
Adjustable screen brightness, and a foldable hook to hang the gauge during work.
Highlights
Dual Pressure Test
Low- and high-pressure lines are read on separate displays.
Dual Temperature Test
Each display also shows the temperature of its line.
Three Working Modes
Refrigerant measurement, vacuum measurement and leak detection.

Good to Know
Care
- Operate according to the instructions or under the guidance of a qualified technician.
- Keep the display clean; wash the case and connectors with a slightly alkaline detergent or soapy water.
- Check the gauge regularly to confirm its accuracy, and handle it gently to avoid shocks and drops.
- Close all valves after use, and cap the fittings when not in use to keep debris out.
- Clean or replace the refrigerant hoses regularly and remove dirt from the valves.
