Electronic halogen leak detector for car AC refrigerant tester1、Leak detector adds some convenience features: seven levels of sensitivity increase sensitivity by 64 times, and a three‑color LED indicates the extent of leakage over a wide range in a progressive manner. It is also used to display sensitivity levels and battery power; Touch keyboard for all operations; The thin and long shape design greatly facilitates the use and maintenance of users; The indicator light is in the direct view range during use, very convenient. 2、SF6 qualitative leak detector has 30 years of leak detector manufacturing experience. As the stable and sensitive negative corona leak detector, we are proud to provide this tool. We put all our experience and years of customer feedback into this product, hoping to provide users everything: price, performance and reliability. 3、The core of this device is an microprocessor. Its digital signal processing technology makes it better than the control circuit and sensor head signal. In addition, the number of components used in the circuit is reduced by approximately 40%, resulting in improved reliability and performance. The microprocessor monitors the sensor head and battery voltage values in real time, up to 4,000 times per second, compensating for even the tiniest fluctuations in the signal pulsation. 4、The refrigerant gas leak detector can be used for leak detection of other systems and storage/recovery containers. This product works on all halogenated refrigerants, including chlorine and fluorine. Including but not limited to CFCs such as R12, R11, R500, R503, etc. HCFCs such as R22, R123, R124 R502, etc. HFCs, such as R134a, R404a, R125, etc. 5、Wide range of applications. Detection of ethylene oxide leaks in hospital disinfection equipment (detection of halogen‑carrying gases). Test SF‑6 in the high voltage circuit breaker. Detection of most gases containing chlorine, fluorine and bromine (halogen gases). Test cleaners used on dry cleaning equipment, such as carbon tetrachloride. Detection of halogen gases used in fire extinguishing systems.
