AUTOOL LM120+  Refrigerant Gauges Digital HVAC Gauges Features

✅ Dual pressure and temperature testing: The LM120+ is capable of measuring high and low pressures, holding pressure leak testing, condensing pressure and temperature measurement, evaporating pressure and temperature measurement, and corresponding line temperatures. 

✅ Multiple test modes: Measurement of dual pressure and temperature, vacuum, leak detection, holding pressure leak test, multi-unit conversion. 

✅ Built-in refrigerant database: Built-in 32-bit digital processing unit and 89 kinds of refrigerant database, it can calculate subcooling and superheating temperatures, and is convenient to read the data directly during operation.

✅ High-precision display: Adopting a large-size LCD liquid crystal display that supports backlighting, the data display is clear and easy to read. 

✅ Industrial-grade design: Durable valve switch and 1/4-inch standard interface ensure the durability of the refrigerant meter 

✅ Preferred materials: high-strength engineering plastics, flexible non-slip silicone design and ergonomic housing design. 

Evaporation Pressure&Tempe test
The maximum pressure when the refrigerant changes from liquid to gas. The lowest temp when the liquid becomes gaseous.（The lower the pressure and temp of the evaporation are, the more efficient the refrigeration cycle and the greater the refrigeration capacity will do.）
Condensing Pressure&Temp Test
The minimum pressure when the refrigerant changes from gas to liquid, and the maximum temp when the gas changes to liquid. (The lower the pressure and temp of condensation are, the higher the efficiency of the refrigeration cycle and the greater the refrigerant capacity will do.)
High/Low-pressure temperature test
The temperature of the AUTOOL LM120+ Digital Refrigeration Manifold in the high/low-pressure pipelines of the air conditioning system.
Pressure leakage test
Calculate the pressure difference between the initial test pressure and the second test pressure to determine if the refrigerant is leaking.
Type Setting&Observable window
AUTOOL LM120+ Digital Refrigeration Manifold can be set according to the type of refrigerant that the car needs to fill; The refrigerant filing status can be observed through a visible window.
Smart Digital Display
The intelligent digital display of the test results of the pressure and temperature of the air conditioning system reduces the cost of time.
