The Model 16600 electronic leak detector features an easy-to-hold case and a 16-in. gooseneck probe that keeps its shape for one-handed operation, the manufacturer says. Helping pinpoint leaks are audible and visual leak indicators, as well as threshold balancing and volume control. The sensing tip is built with a mirror finish for high sensitivity and can be cleaned for longer life. The unit can be used for CFC, HCFC, and HFC refrigerants.
