Gran herramienta para HVAC
Por mucho, mejor que los detectores que tiene que “oler” el refrigerante. Es súper rápido hacer verificaciones con este equipo y es muy sensible. Excelente herramienta de diagnóstico para los trabajamos en HVAC.

Found a leak soap or UV dye wouldn’t. It’s made for HVAC, not tires!
Fantastic item. Just shut off fluorescent lights first, they put off a ton of noise. Found a leak in less than 60 seconds. People who have issues with this don’t know how to use it properly or patiently. It’s really not complicated. I had a leak I couldn’t find with UV dye or soap. This saved my behind and made a happy customer with the first use.

Not able to detect tiny leak rates
It does work as advertised but only if the leak rate is large enough to generate where it can detect it. The issue is there is no specifications for that such a grams/year which we in HVAC/R refer to. It does serve a purpose if used within its capability. Good for detecting motor bearing noise, ultrasonic devices, and could detect nitrogen pressurized equipment. Water on the tubing and cores does aid in locating the leak. Using headset is a must. . To give an example of a tiny leak rate where it did not detect it, see attached video.
