LotFancy Freon Leak Detector for Halogen Gas Leakage Refrigerant Leak Detector HVAC for CFCs HCFCs HFCs R134a R410a R22 R11 Tester High Accuracy with Indicator Light

Note: (batteries NOT included) The battery voltage instructions: The lights which on the front of panel used in warning leakage and battery voltage instructions. Green - battery voltage normal, suitable for work;Orange - battery voltage close to the limit, need to work as soon as possible replacement Boot reset/automatic follow circuit: Boot reset: this instrument after startup, can automatically adjust to within 6S ignore probe existing circuit, enter detection concentration level the refrigerant state, if users in leakage source can be conveniently near boot, looking for higher levels of the leakage source. The device also moved to clean the air can be powered by adjustment to maximum sensitivity, than zero concentration level, right now the leakage can be detected. automatic follow circuit: in this instrument in detection condition, automatic circuit will follow the environment changes, the gas concentrations of halogen to prevent false-negatives. Leakage warning:When the gas leakage are discovered, "di di" sound will become more hurried, leakage, "di di" sound more rapid. Meanwhile lights flash.
