Freon Leak Detector WJL-6000 Refrigerant HVAC Leak Detector Halogen Gas Sniffer Automotive Gas Finder Halogen Leakage Tester Checker for R134a R410A R12 R22 R404A Featuring with a corona sensor and advanced leak detect technology, WJL-6000 is our reliable product with the functions of easy operation, stable function and great performance; It’s an ideal and economic freon and halogen leak detector. It is widely applied on pipe leakage, automobile air conditioner, cold storage, refrigerator repair and so on. Features: 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. Widely Use: All halogened refrigerant :R11, R22, R134a, 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. Please note this monitor is equipped with a high-volt electrical sensor, this kind of sensor is designed to be used without contact with the skin or other surfaces, otherwise, error alarm might be triggered.
