AUTOOL LM70 Smart Digital Manifold

The AUTOOL LM70 Smart Digital Manifold is an intelligent refrigerant gauge for automotive air conditioning, home air conditioning, and refrigeration maintenance. It combines pressure measurement, temperature measurement, vacuum monitoring, refrigerant filling, pressure leak testing, and system debugging in one compact dual-channel tool, helping technicians and beginners evaluate A/C system status more accurately and efficiently. LM70 provides one-stop support for A/C and refrigeration diagnostics, including high-precision pressure measurement, dual-channel monitoring, automatic superheat / subcooling calculation, pressure leak testing, vacuum monitoring, and refrigerant charging support. LM70 includes mainstream refrigerant data, pressure / vacuum / temperature unit switching, a high-brightness backlit display, and three-color refrigerant hoses for workshop and outdoor use. LM70 is suitable for automotive A/C repair, household air conditioner maintenance, refrigeration equipment debugging, and routine cold storage maintenance when used within the rated pressure range and with the correct refrigerant.
