Abstract
A hand held refrigeration fluid leak detector for observing and detecting optical fluorescence resulting from optical excitation of the leaking refrigeration fluid provides single hand operation for a user while holding the main body of the detector with either one of two hands. The flexible stalk is coupled to the main body and to a head containing an LED light source which provides spectral emissions in the UV to blue range. In one embodiment, the hand held detector includes a gas detector.
