Autool LM120+ | AC Manifold Gauge
The Autool LM120+ is a digital aircomanometer, designed for measuring pressure and temperature in air conditioning and cooling systems. The device is equipped with a sensor for measuring vacuum and pressure, and can display measurements in various units such as Kpa, Mpa, bar, inHg, and PSI. The pressure test range runs from 0 to 6000 Kpa and the vacuum range from -101 to 0 Kpa. Temperature can be measured in a range from -40°C to 150°C.
This manifold meter features an integrated database with data of 89 different refrigerants, including the corresponding evaporation and condensation temperatures. The device has a digital LCD screen with backlighting for clear reading of measurement results. Additional functionalities include a pressure leak test, measuring evaporation and condensation pressure, and an observation window to check the status of the refrigerant filling. The housing is made of engineering plastic and has an anti-slip design.
Application and functionality:
The LM120+ is used for the installation, testing, and maintenance of cooling equipment such as air conditioners and refrigeration storage systems.
- Dual pressure and temperature measurement: Simultaneous measurement of high and low pressure and two temperatures (evaporation and condensation).
- Pressure leak test: Calculates the pressure difference between the initial and second test pressure to determine if there is a leak in the refrigerant system.
- Evaporation pressure and temperature test: Measures the maximum pressure and lowest temperature when the refrigerant changes from a liquid to a gaseous state.
- Condensation pressure and temperature test: Measures the minimum pressure and maximum temperature when the refrigerant changes from a gaseous to a liquid state.
- Refrigerant selection: The user can select the specific refrigerant from the built-in database of 89 types for accurate measurements.
- Observation window: A sight glass allows visual inspection of the refrigerant liquid flow and status during filling.
- Multi-unit conversion: Pressure and temperature measurements can be switched between different units (Kpa/Mpa/bar/inHg/PSI and °C/°F).
