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

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.

Only complaint I have with this, is the calibration takes 30 seconds outdoors but other than that it’s been working well for home inspections. Sensitivity on this is very dialed in as well.

Why did you pick this product vs others?:Name.. Klein tools have always been top quality for me.Works well:Previous tester had false positives. This one works great,

I use this to look for leaks on refrigeration systems using R290. It works great but the power button is very sensitive. It it's soft case if anything bumps the front the power goes on and drains the batteries. Since I only use this for certain jobs I have to pull the battery pack out of the back so they will still have a charge the next time I need it.

Had a natural gas leak that came and went. Many people trying to find where it was coming from but to no avail. I took a shot with this thinking that maybe this device would get me in the vicinity. I have had a few Klein tools and have had no issue with any of them. This worked flawlessly. As instructed, I set the meter to high sensitivity and walked through the 1800 sq ft open space. Turns out, an adjacent room was where the leak was located coming from the 1.5" mainline coming into the building from the meter. The leak was inside the block wall. Without this meter, there is no way I could have found it in a brick wall. After making the repairs, I tested the area again. No leak, no smell. So thankful that the tool was affordable and that our facility is safe.

WORKS GREAT, DETECTS VERY SMALL GAS LEAKS.

Why did you pick this product vs others?:My very good plumbers embarrassingly didn't own one of these tools. We used it and immediately found 2 leaks they were unable to detect.

Works great, if it works. I'm on my 3rd one and it arrived DOA. Brand new batteries and all. Between that and the durability of the end & gooseneck, I'm over these.Sucks because normally Klein is the go to.
