I was smelling a faint gas smell in the basement and just ordered this on Amazon today. Thank you for this review video!

I need to quit watching these videos because I end up buying the product right away and it makes for large Amazon bills. But this is a nice tester to have around the house.

I just bought that and did testing with R22, R410A, and R407A. All these gases made the PT520A light up like a pinball machine. I also tried it with a few empty tanks of R22 and R410A where they were empty but some some vapor pressure remained. Opened the valve just a tiny crack and this device indicated the gasses immediately. It also picked up the micro leak on my test evaporator core. In fact, it’s just about as sensitive to most refrigerants as my Fieldpiece DR58 which is about $325. If they made this with a smaller tip, it could be given a different model number and marketed as a refrigerant leak detector.

I’d want something that detects less than 50ppm for natural gas (furnace)

I didn't see refrigerants on amazon. Does the manual say r-32?

It is a shame it does not tell you what chemical/substance it is actually detecting. You may want to shut one off.
