CPU-1G HVAC Freon Leak Detector Halogen Gas r HVAC Refrigerant AC Sniffer R22 R410A R134A

Excellent tool and effective. cheaper on their website 10 percent coupon no tax free shipping so only 54 bucks total and it comes very fast but maybe not quite as fast as prime tho. I have been using elitech tools this season I totally love their SMG-1L it was 20 dollars cheaper on their site though. and i really just love them so far. This so far is my favorite leak detector. it doesnt make you wait to tare out or whatever you just turn it on and turn it off. Only downside is it does look a little silly and that silly noise. It doesnt look all expensive and high end but that dont matter to me at all because it works hands down the best so far. I have found a very lot of leaks even through walls with it extremely effectively. I treat it like a baby and take care of it. I keep it in the box and then keep it where nothing can even bump into it. Ya im overly caring of it but this one is a special very important tool that i have to rely on to not lie to me. If i have an evap coil leak i have to be certain and with this thing I feel 99 percent secure in my diagnosis. To be honest you can be hard on it too its very rugged and durable. HVACR tech 20 years i can tell you this is a well made tool despite being cheap and coming off a little goofy looking and sounding. Their digital gauges havent lied to me one bit either i know that the number it displays is 100% the number it really is.

Absolutely the best leak detection unit around very impressed

It does work pretty well. I have noticed that if you get too close to anything it will go off. There is also not any volume control and it beeps the entire time you’re using it. I have used this detector a few times now and it has done its job. I would recommend this as a starter tool or if you’re not going to use it often

Worked great

My AC tech said my evaporator coil had a leak and he held up some random device he said was a coolant leak detector and showed me the "leak." To be honest the thing he had looked more like a voltage meter lol, but I'm also not really that handy when it comes to HVAC. I knew eventually I'd have to replace our AC systems but wasn't planning on doing it this soon.So I bought this thing and decided to check for a leak in the same spot after the tech was gone to see for myself if there really was a leak or if he was just BS'ing me. Nope - there really was a leak and this thing was super easy to use. I'm gonna keep it handy in case I have future problems or have an issue with the AC in our vehicles. A little pricey but worth it for the peace of mind that I wasn't being lied to by the mechanic.
