The Autool LM120+ is the advanced version of the digital air conditioning pressure gauge, designed for measuring pressure and temperature in air conditioning systems and refrigeration installations. The pressure test range is 0 to 6000 kPa, the vacuum range -101 to 0 kPa, and temperature is measured from -40 °C to 150 °C.
This manifold gauge features an integrated database with 89 refrigerants, including their corresponding evaporation and condensation temperatures. Additional features include a pressure leak test, evaporation and condensation measurement, and a sight glass for visual inspection of refrigerant charge. The housing is made from engineering plastic with a non-slip design.
KEY FEATURES
THINGS TO NOTE
Applications and functionality
The LM120+ is used for the installation, testing, and maintenance of cooling equipment such as air conditioners and refrigerated storage systems.
- Dual pressure and temperature measurement: Simultaneous high and low pressure readings and two temperature measurements (evaporation and condensation).
- Pressure leak test: Calculates the pressure difference between initial and second test pressure to detect leaks.
- Evaporation pressure and temperature: Measures the maximum pressure and lowest temperature at the liquid-to-gas transition point.
- Condensation pressure and temperature: Measures the minimum pressure and maximum temperature at the gas-to-liquid transition point.
- Refrigerant selection: Choose from 89 types for accurate measurements.
- Sight glass: Visual inspection of refrigerant flow and status during charging.
- Multi-unit conversion: Switch between kPa/MPa/bar/inHg/PSI and °C/°F.
