Refrigerant Gas Leak Detector






1 The leak-detect in vocation of freeze, refrigeration, and air-conditioner

2 The leak-detect for air-conditioner in the car

3 Detect leaks in other systems and storage/recovery containers. It will respond to all halogen gases (including Chlorine of Fluorine) refrigerants. This includes, but is not limited to:

CFCs e.g. R12, R11, R500, R503 etc

HCFCs e.g.R22, R123, R124,R502 etc

HFCs e.g.R134a, R404a, R125 etc

And other mixtures, e.g. AZ-50 HP62 MP39 etc

4 Detect ethylene oxide gas leaks in hospital sterilizing equipment (it will detect the halogenated carrier gas)

5 Detect SF-6 in high voltage circuit breakers

6 Detect most gases that contain Chlorine, Fluorine, and Bromine (halogen gases)

We are proud to present this tool as the most stable and sensitive negative corona leak detector ever made. We have incorporated all of our experience and years of customer feedback into our product, in the hope of providing our valued customers with the best of everything: price, performance and reliability.

An advanced microprocessor is the heart of this unit. Its digital processing permits better management of circuitry and sensing tip signal than ever before possible. Additionally, the number of components used in the circuit is reduced nearly 40%, increasing reliability and performance. The microprocessor monitors the sensing tip and battery voltage levels 4000 times per second. Compensating for even the most minor fluctuations in signal. This translates into stable and dependable tool in almost any environment.

Convenience features have been added to enhance the usability of the CPU-1G. Seven levels of sensitivity provide an increase of 64 times from level 1 to level 7. Unique Tri-Color LED’s show a progressive and wide ranging leak size indication, communicate the sensitivity level, and provide a true voltage indication of battery power level. A tactile keypad controls all functions of operation. A revolutionary new case design gives the user grip a control, and places the visual indicators in direct sight during use.
