The Autool LM120 is a digital air conditioning manifold gauge for installing, maintaining and inspecting refrigeration systems and air conditioning units. The gauge measures pressure in a range of 0 to 6000 kPa and vacuum from -101 to 0 kPa. The temperature range spans -40 °C to 150 °C.

The device is equipped with a built-in database of 89 refrigerants with corresponding pressure and saturation temperature data. It features dual pressure and temperature measurement, vacuum measurement, pressure loss testing and a sight glass for visual inspection of refrigerant status. All measurements are clearly displayed on the backlit LCD screen.

KEY FEATURES

89 refrigerants in database — automatic calculation of saturation and condensation temperatures.
Dual pressure & temperature — simultaneous HP/LP and saturation/condensation readings on one screen.
Pressure loss test & vacuum — check for leaks and detect moisture or non-condensable gases.

IMPORTANT NOTES

Batteries not included — 4x AA batteries to be purchased separately.
Professional use only — F-gas work in the Netherlands requires certification for air conditioning system servicing.
Base model — for extended features see the LM120+.

Application and functionality

The LM120 offers various measurement modes for comprehensive air conditioning system analysis:

  • Pressure and temperature test: Simultaneously measure pressure and temperature on both the high-side and low-side of the system.
  • Evaporation pressure and temperature (Ev): Calculates and displays the transition from liquid to gas.
  • Condensation pressure and temperature (Co): Calculates and displays the transition from gas to liquid.
  • Pressure drop test: Leak test via pressure differential (ΔP) over a set period.
  • Refrigerant selection: Choose from a database of 89 types for accurate calculations.
  • Vacuum measurement: Check for the absence of non-condensable gases and moisture.
⚠️
Important: In the Netherlands, work on systems containing F-gases (including most automotive refrigerants such as R134a and R1234yf) requires STEK certification for the technician.
