Digital HVAC Manifold Gauge Set Refrigeration A/C Pressure Vacuum Leakage Tester

AUTOOL  LM150 Digital Refrigerant Meter is equipped with a high sensitivity sensor that can accurately detect key parameters such as refrigeration system pressure and temperature. Integrated with dual pressure/dual temperature detection function, it can display high and low pressure pipeline pressure and pipeline temperature data in real time. Equipped with 93 kinds of refrigerant database, compatible with mainstream refrigerants such as R1234yf and R134a. With refrigerant pressure leakage detection and refrigerant charging and vacuum function, it can accurately diagnose the air conditioning system, which is one of the necessary tools for refrigeration maintenance engineers and air conditioning installers.

AUTOOL LM150 Digital Manifold Gauge Advantages
✅ Multiple unit options: Switch between units such as psi, kpa, mpa, bar, inHg, and temperature units such as ℉ and ℃.

✅ 3.5-inch high-definition display: Designed with a backlit screen so it can be used even in dark environments. The display divides the test results into lines, making the data more intuitive and clear.

✅ V Shaped Ball Valve Opening Design: AUTOOL LM150 high and low pressure valve with V-shaped opening design can easily control the valve switch, eliminating the tedious knob action, the amount of refrigerant charged is easier to control than ordinary knob valve refrigerant meter, easy to operate and more durable.  

✅ High-quality materials: AUTOOL LM150 is made of sturdy housing with IP54 protection rating and flexible non-slip silicone design for comfortable operation.

✅ Clamp-on Probes: The two wired temperature clamp-on probes in the AUTOOL LM150 kit measure evaporation and condensation in real time.

✅ Versatile: It measures HP/LP line temperature and pressure, evaporation/condensation temperature, vacuum pressure/percentage, leakage, and supports 93 refrigerants with a unit switch.

✅ 3-year warranty：For non-human-caused damages, AUTOOL promises to resend the parts free of charge within 3 years. If you have any request, welcome to contact us, we will reply you as soon as possible within 24 hours.
