These units usually sit in a drip pan or similar location where people want to know if there is a leak. If they end up in the thinnest pool of liquid, they will alarm. They use a leak detector looking at an LED, and if that light path gets altered at all, then it knows there is a liquid there. With that, it will detect any liquid as long as it is not exposed to excessively high or low temperatures. *Note: These units are not rated to operate in a hazardous, potentially explosive environment or for flammable liquids.
