AUTOOL LM120 AC Manifold Gauge Refrigerant Identifier

The AUTOOL LM120 AC Manifold Gauge is a professional digital manifold gauge for installing, testing, and maintaining refrigeration systems such as automotive A/C systems, air conditioners, and cold storage equipment. It combines dual pressure testing, dual temperature testing, vacuum measurement, pressure leak testing, refrigerant filling support, multi-unit conversion, and a built-in refrigerant database in a compact handheld body. Check pressure range, hose rating, tested equipment rating, operating environment, and personal protection before using the LM120 digital HVAC manifold gauge. LM120 is designed for stable digital A/C and refrigeration system service with high-strength materials, backlit data display, multi-mode testing, refrigerant data support, and practical field operation. Review the core pressure, vacuum, temperature, refrigerant database, size, and power specifications before selecting the LM120 digital manifold gauge. LM120 is built for A/C and refrigeration system service. Use the correct mode, accessory setup, refrigerant selection, and safety procedure for each test. Compare LM120 with related AUTOOL air conditioning system testers before choosing refrigerant modes, hose accessories, temperature clamps, pressure units, and program control functions.
