Review on Enhanced Elitech ILD-300 Infrared Refrigerant Leak Detector: Advanced HVAC Halogen Tester with Selectable Gas Functionality by Marcus Barlow

Using a leak detector for R22 and 410a. So far this is one of the best I've bought. You'll have to lower the sensitivity once you find the area you want, but that's easy. This has reduced our time on the site and will easily pay off. Our engineers are more confident in selling a replacement component after verifying actual unrecoverable finned coil leaks.
