Review on 🕵️ Elitech IR-200 HVAC Refrigerant Leak Detector - Advanced Halogen Leakage Tester, AC Sniffer with Infrared & Heated Diode Technology by Phillip Jaylon

This is a good product, durable and well made. Any leak detector requires some skill - you need to know how to do it - so experiment with it if you've never used one. I like that it has two modes as one is more sensitive to let you know you are in a common leak area and the other helps locate it. Now, nothing beats blisters appearing once you've checked them out by spraying a soapy solution on the affected part, but I like having a tool that lets me know I'm in the area.
