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.
Claims14
A hand held refrigeration fluid leak detector comprising:
- a main body having at least one surface suitable for holding;
- a head having at least one LED light source with a spectral emission in the UV to blue range mounted therein;
- and
- an elongated flexible stalk coupled at a first end to the main body and at a second end to the LED-containing head so as to permit the head to assume a variety of angular positions relative to the main body;
- the holdable surface of said main body being electrically isolated from the outer-surfaces of said head and stalk, wherein at least one of the head, the flexible stalk, and the main body has an electrically non-conducting outer-surface.
