1. AUTOOL LM120+ AC Manifold Gauge

The AUTOOL LM120+ AC Manifold Gauge uses a built-in pressure sensor to detect the vacuum pressure within the system and convert the pressure signal into an electrical signal. The microprocessor processes and calibrates the signal, then displays the vacuum level as a numerical value on the screen. It supports intelligent features such as data storage and multi-unit switching, making it convenient for quickly detecting the sealing integrity and vacuum effect of the air conditioning system.
