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.

[@DN19756]

That's the game. You're watching an ad. He said Toptes sent him the small unit, my assumption is they sent him the PT520A. I also assume most products reviewed are provided by the company, and not purchased with his own money. I don't hold it against him. I end up purchasing a lot of things I see on here because they're pretty cool. I just wish there was some disclosure.

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

[@bizzfo]

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

[@zjenji]

Exactly

[@CJINW]

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

[@lastbesttool]

I believe that would take a gas chromatograph. I have a cheap one and still it was $1500 and couldn’t quickly identify a substance.

[@jakechef994]

how very relevant today gotta get me 1 of these thanks doc👍

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

[@lastbesttool]

The manual says "Refrigerants (contain propane in)" I assume that would be R290 etc. R32 does not contain propane so it's less flammable but more toxic. I guess you have to pick your poison.

[@FreonChugger]

@@lastbesttool R-290 (Propane) is an A3 refrigerant. The 3 indicating it's flammability (High Flammability) and A being indicating it's toxicity. A is non-toxic while B is toxic. R-717 (Ammonia) is classified as B2L. (2L being a new regulative classification to make the dunces in government feel better about themselves rolling out flammable refrigerants for residential/automotive use.) R-32 is classified as A2L (Low "low" Flammability, Non-Toxic) and is one of the refrigerants replacing R-410 which is classified as a A1 refrigerant (No Flammability, Non-Toxic.) Cheers.

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.

What about 404a, 134a, or 407c?
