Ugh. I just tried to use my SLR8 leak detector and couldn’t find anything on a small R22 package unit. Getting a bit suspicious I checked it’s efficacy on a hose fitting I loosened. I could hear the gas coming out but the detector barely responded. It’s less than a year old so it shouldn’t need a new sensor. It’s not the first SLR8 I’ve had lose ability after a year or so. Anyone have a suggestion for another more reliable detector? I’m going to get a new sensor for this one but I want another one to use when this one doesn’t pick up a leak.
