AUTOOL LM150 Digital Manifold Gauge is ideal for HVAC refrigerant installation and maintenance. It offers dual pressure/temperature testing, digital readout, multi-mode capability and refrigerant database. Constructed of durable, non-slip material, it features a high-precision unit, backlit LCD, long-life valve switches and a 1/4-inch interface for stability and ease of use.

With pressure testing, temperature testing, refrigerant charging, evacuation, holding pressure leak testing and a built-in database of 93 refrigerant NIST standards, the gauge is the perfect aid in the repair and maintenance of air conditioners, refrigeration equipment and heat pumps.

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.

✅ Three-year warranty, lifetime maintenance: For non-human-caused damages, OUTOOL 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.
