Elitech LD-200 - Refrigerant Leak Detector 

Refrigerant Leakage
Refrigerants are the backbones of a refrigeration system, their main purpose is to remove the heat from the air. When there is refrigerant leakage, the air conditioner runs longer to compensate, consumes more energy, and the component may get damaged. Large leakages can also lead to environmental hazards. 

Perfect Fit
The Elitech LD-200 is designed to fit on your hand allowing you have a firm grip when detecting the leakage. The most unachievable places will be easily accessed with the LD-200

Even the small leaks 

The LD-200 can detect leaks as small as 3g/yr with a very fast response (<3s) and all types of CFCs, HCFCs, HFCs, CH refrigerants. A bright backlight LCD screen and customizable alarm. Everything you need to find all leakages. This is achieved through the employment of a high sensitive heated diode sensor combined with a sophisticated microprocessor-controlled circuit.
