Review on π Elitech CPU-1G: Advanced Halogen Gas Tester, HVAC Leak Detector for R22, R410A, R134A Refrigerants by David Herrera
Leak check after leaving A/C service
I use this to check valve caps for leaks every time after leaving A/C service. Some air conditioning service companies do not fully tighten the valves. So you get a repair call after a few years. With this gauge I can check if the valves are fully closed and close them if they are not closed.
- Trial period for one year
- Safety
