Review: Durable - I have used the device on many units and have detected leaks when needed! Super bright and very loud when detecting a small or big leak. The quality is worth the money! Its a strong high functioning unit and will recommend to everyone that needs one with in budget!
Review: Sensyx Rechargeable HVAC Refrigerant Leak Detector, SFD201 - It's a good refrigerant, gas leak detector. However you have to turn it on in the same area but not too near to the A/C or stove that you are checking. I used it to check if the evaporator coil of the mini split inside my room is leaking. At first it gave me false positive because I turned it on outside the house, I misunderstood the instruction I thought it needs fresh air outside as the base reading. When I went inside the house it beeped right away and it also has a warm up period of 30 seconds I believe. You can turn off the sound (beeping) if it annoys you. It detects the refrigerant or gas but it won't tell you what kind it is. After that I turn it on in the same room as the evaporator coil and it didn't detected any leaks, I thought it might not be working properly so I breathe into the nozzle and it detected the CO2. So I guess it's working properly. It's rechargeable so you don't have to worry about batteries and it also comes with a case. I only bought it for peace of mind I don't wanna breathe in refrigerant because they're basically poison. Thanks.
