AUTOOL LM120+ Refrigeration Digital Manifold HVAC Gauges 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]: For damage caused by non-human factors, AUTOOL promises to resend parts for free within 3 years. For any needs, you are warmly welcomed to contact us and we will get back to you ASAP within 24 hours.ght.

  • Question 1: How to verify the accuracy of the temperature?
  • Answer: The temperature measured by the gauge is allowed to deviate by 3% from the actual temperature. There is a simple way to verify the accuracy of the temperature: Take out the black wire on the temperature clamp and put it in the boiling water. If the temperature is 100 degrees Celsius or the error is plus or minus 3%, it is normal. NOTE: Please pay attention to temperature unit conversion between Celsius/Fahrenheit.
  • Question 2: Why does the pressure value fluctuate slightly? Is it a leak or is the data inaccurate?
  • Answer: According to the current level of hardware processing in the industry, it is difficult to achieve a 100% completely sealed valve on the market. The sealing degree of our guage hardware can only reach 99%. But these slight leaks will not affect the use.
  • Question 3: Does this gauge have a micron reading function?
  • Answer: No, the accuracy of this refrigerant manifold gauge can only reach the accuracy equivalent to this unit: -101 Kpa-0 Kpa.
