Hunting down tiny refrigerant leaks just got easier. The NAVAC NML1 is a solid, rechargeable leak detector that’s perfect for HVAC pros or serious DIYers. It uses a semiconductor sensor that’s sensitive enough to find leaks as small as 0.1 oz per year—and the sensor lasts a long time (1500+ hours). Works with all common refrigerants: CFC, HCFC, HFC. The sniffing fan pulls in air at about 2 CFM, so you can scan joints, valves, and lines quickly. It’s lightweight (only 0.77 lbs) and the probe is about 16 inches long, so you can reach into tight spots. Battery is lithium-ion and rechargeable. Comes with a 1-year warranty. No more guessing where that leak is—this thing helps you find it fast and get the job done.
