Widely use.:All halogened refrigerant :R11, R22, R134A, R404a, R410A,R1234yf,SF6( HFCs, CFCs,HCFCs and blends). It can be used for almost all air-conditioning refrigeration, including car air-conditioning, household air-conditioning and equipment refrigeration.

Instant responee.:Warm up 6 seconds & response time 3 seconds. Upon initial switch-on, keep in 6s and enter into the best state of detection. Place the sensing tip near a known leakage area and switch on, can find a higher concentration of leakage. When the gas leakage are discovered, Will hear "di di" sound . More refrigerant leak, more rapid, meanwhile the indicator light flash quickly.

High sensitivity.:Perfect IC circuit design assure high sensitivity(0.2oz/year).7 adjustable sensitivity.Flexible probe can reach to almost any awkward corners or space. It also can automatically adapts to the new concentration. (4*AAA Alkaline batteries not include).

Visual &Audible alarm for leakage and battery indicator. A flexible probe around 7.9-inch allows detections in difficult and hard-to-reach areas. The leak detector features an automatic circuit and a reset function that set itself to ignore the ambient level of Halogen gas.
