AC Refrigerant Leak Detector Elitech CPU-1G is a new developed intelligent halogen leak detector. The advanced microcomputer dealer manage the detection better. It's the most reliable and stable leak detector based on the theory of Negative Corona Discharge, giving great expression to easy operation, stable function and high performance. It is a portable sensitive device designed to pinpoint the location of halogen refrigerant leaks in refrigeration systems. These include automotive air conditioning, refrigerators, freezers, vehicle refrigeration systems and home, office, and industrial cooling/refrigeration systems, where halogen is used as the refrigerant. This device is a necessity in the tool box to technicians who do services in the refrigeration and air conditioning field.

Technical Characteristics: 
Power supply: 2 size"C" Alkaline Batteries
Warm-Up Time: 6 seconds
Application of refrigerant: 
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 perchloroethylene.
Sensitivity: 3g/yr of R-134a(ultimate Sensitivity); 6 g/yr of R-134a(max sensitivity)
Battery Life: 50 hours, under typical intermittent operation
Probe: Flexible gooseneck, 14 inch
Visual and Audible indicators: 
Power & Battery: Tri-color LED display (according to the glowing sequence of color: red, green, and orange)
Relative Leak Level: 7 levels of increasing LED display
Visual -7 LEDs progressively glow from left to right when halogen level Increases
Audible- Beep-sound, rate change along with the visual LED, increase from its idle rate to a higher frequency when higher levels of halogen are detected

Operating Environment: 
Temperature: 0°C to 52°C
Humidity: 20 to 80% RH, non-condensing
The forward direction air flue supplied by mechanical pump improves and enhances the detection sensitivity.

Control Switches: 
Power: Switch the detector ON/OFF
Sensitivity: Relatively change the response to halogen level.
Reset: Reset the background halogen level at the tip to"zero", any level higher than this "zero" is considered to be a leak and trigger the alarm.
Muse: Set the buzzer sounds or not during the detection process.
