The Inspector incorporates electronic and UV technology into one unit, ensuring that even the toughest leaks can be found, said the company. The leak detector offers six levels of sensitivity (15 levels of detection) with a tri-colored LED indicator. This allows the leak detector to pinpoint leaks as small as 1?10 ounce (3 grams) per year. The ultrabright UV light is built into the end of the probe, allowing easy access into tight areas. Incorporating both electronic and UV technology into one unit ensures that even the toughest leaks can be found. The leak detectors identify all refrigerants (CFCs, HCFCs, and HFCs) and include a custom-molded carrying case.
