Digital Refrigerat Manifold Gauge HVAC System Vacuum Pressure Temp Leak Tester
Description：
AUTOOL LM120 Digital Refrigeration Manifold is an auxiliary instrument for the installation, testing, and maintenance of refrigeration equipment such as air conditioners and cold storage. The instrument is capable of double pressure test, dual temperature test (need test clip, not include), digital readout, multi-unit switching, multi-mode function, and built-in refrigerant database.
Features：
1. [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.）
2. [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.)
3. [High/Low-pressure temperature test]: The temperature of the AUTOOL LM120/LM120+ Digital Refrigeration Manifold in the high/low-pressure pipelines of the air conditioning system.
4. [Pressure leakage test]: Calculate the pressure difference between the initial test pressure and the second test pressure to determine if the refrigerant is leaking.
5. [Type Setting&Observable window]: AUTOOL LM120/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.
6. [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.
7. [Three Years Warranty, Lifetime Maintenance].
