Autool LM120 | AC Manifold Gauge
The Autool LM120 is a digital aircomanometer, designed for measuring pressure and temperature in cooling systems. The device is equipped with a built-in database that supports 89 types of refrigerants, based on the US NIST standard. The meter can simultaneously measure and display dual pressure and dual temperature on a large backlit LCD screen. Functions such as the calculation of superheating and subcooling are integrated for a complete analysis of HVAC systems.
In addition to the standard measurements, the LM120 offers specialized test modes. The instrument can perform a vacuum test to check the vacuum level of a system and display the results as a percentage. Another feature is the pressure leak test, which displays the pressure curve in real-time to determine the speed and duration of a leak. The housing is made of durable plastic and has an anti-slip and anti-drop design for use in demanding work environments.
Application and functionality:
The Autool LM120 is used for installation, testing, and maintenance of cooling equipment such as air conditioners, cold rooms, and industrial refrigeration systems. The various modes make it a versatile diagnostic tool.
- Pressure and temperature measurement: Simultaneously measures high and low pressure and corresponding temperatures. Automatically calculates the degree of superheating and subcooling.
- Built-in refrigerant database: Contains pressure and temperature data for 89 different refrigerants, eliminating the need for manual lookup tables.
- Vacuum test: Measures pressure during system evacuation and displays the vacuum level in percentages, helping to determine if the system is fully free of air and moisture.
- Pressure leak test: Detects pressure loss in a system. It measures the initial pressure and tracks changes over time, recording leak duration and pressure drop.
- Multifunctional modes: Easily switches between refrigerant pressure mode, vacuum percentage mode, and leak detection mode.
- Digital display: A large LCD screen with backlight ensures clear reading of all measurements, even in low light.
