AUTOOL LM100 Smart Digital Vaccum Gauge

AUTOOL LM100 Intelligent Digital Vacuum Gauge is a powerful digital vacuum gauge for refrigeration, HVAC, and automotive A/C service. Built with high-strength engineering plastics, soft non-slip silicone, a brass valve body, and a foldable hook, it combines rugged durability with comfortable handheld operation. Equipped with a high-precision sensor, it delivers measurement accuracy up to ±0.2% and resolution as fine as 0.1 mbar. The 2.8-inch backlit display, evacuation mode, pressure retention test mode, one-button 7-unit switching, automatic sleep function, and LM130 data transmission support make it a compact and practical tool for vacuum monitoring and refrigeration system sealing checks. LM100 focuses on accurate vacuum measurement, refrigeration system sealing checks, LM130 synchronized data transfer, and portable field operation. LM100 combines high-precision measurement, evacuation monitoring, leak testing, backlit display, unit switching, and practical structure design for refrigeration and A/C service work. Confirm vacuum range, unit support, temperature range, pressure limits, hose pressure rating, display, and operating environment before testing.
