Klein Tools ET120 Gas Leak Detector, Combustible Gas Leak Tester with 18-Inch Gooseneck Has Range 50 - 10,000 ppm, Includes Pouch, Batteries

A little disappointed to find that the batteries that came with the unit were flat and wouldn’t power the unit. Once batteries were changed everything was fine.

I had to weigh up getting in a gas professional to diagnose severity and location of a possible leak and buying this product.. I did the latter, because I was not prepared to wait. I'm glad I did - old gas oven was leaking past 10mill PPM. Turned off at the mains. No other leaks. Really glad I bought into the tool and took care of it myself. I also appeciate having low or high sensitivity. Only criticism would be I'd like a high PPM for the big leak, but really trivial when it's designed for finding small leaks, more than anything.

Excelente articulo y sin problema en el tiempo de entrega

I tired other "sniffers" that were just completely worthless. This tool is very simple to operate and conclusively confirms whether there is a gas leak--and if so, where it is coming from. The variable response alert system shows the intensity of any leak, or even better, no leak at all. It is very clear, thereby imparting full confidence in the results. (Because it showed I did not have a leak at the time, I tested this by opening an unlit gas burner and "searched" for it. It worked perfectly.) An invaluable, easy too use tool for all-important peace of mind. Highly recommend.

No encendió, cambie las pilas y sigue sin encender.
