General descriptions:

The CPU-1G is a newly intelligent halogen leak detector accumulated with many years' experience, the advanced microcomputer processor can manage the circuit and sensor tip signals better, it's the most reliable performance leak detector based on the theory of Negative Corona Discharge, The microprocessor monitors the sensing tip and battery voltage thousand times per seconds, catching even the slightest signal fluctuation. Some convenient functions have been designed to enhance the usability of CPU-1G: Seven levels of sensitivity provide an enhanced max.64times adjustable range from level 1 to level 7.The unique tri-color LED displays the wide range of leaking degree by the way of gradual lighting, and also displays the sensibility difference and actual battery voltage. A tactile keypad can control all functions operation. A brand new shell design makes the operation and maintaining more conveniently.

Applications:
Detect leaks in other systems and storage/recovery containers. It will respond to all halogenated (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…
              Blends such as AZ-50.HP62.MP39 etc…
Detect Ethylene Oxide gas leaks in hospital sterilizing equipment (it will detect the halogenated carrier gas)
Detect SF-6 high voltage circuit breakers
Detect most gages that contain chlorine, Fluorine and Bromine (halogen gases)
Detect cleaning agents used in dry cleaning applications such as per chloroethylene
