What chemicals does the perc detector (PD1) detect?

The perc detector we carry detects other chemicals as well as perchloroethylene or “perc”. It detects refrigerant gas leaks in Air Conditioning and/or Refrigeration systems. These include CFC’s, HCFC’s, and HFC’s. It detects Ethylene Oxide gas leaks, SF-6 found in high voltage circuit breakers, Halon gases which are in fire extinguishing systems, and most other gases that contain Chlorine, Fluorine, and Bromine.
