Electronic leak detector is based on the principle that when halogen vapour is heated, positive ion concentration is increased and this increase is suitably magnified to an audible or visual signal. ... Electronic leak detector is highly sensitive and it can detect leaks as small as 0.25 to 0.50 oz. Per year.
IR (infrared) detectors detect refrigerant by sampling in a sweeping motion to pinpoint refrigerant leaks. IR sensors zero out of held over a leak. The advantage for IR is it triggers the same for all refrigerants unlike heated diode which work better then some refrigerants than others.
What is a halogen detector?
Halogen Leak Detectors Halogen leak detectors are used to detect and identify the specific location of halogenated refrigerant leaks. This type of leak detector is not always permissible in certain settings.
How is a halide leak detector powered?
A device that uses acetylene or propane gas to heat a copper disc in order to detect a refrigerant leak. A leak is indicated when the color of the flame becomes greenish in color.
