TPI 720B Combustible Gas Leak Detector

A combustible spot checker liek this is essential for safety working around heating appliances. As the others have said, typically these are a dime a dozen but TPI is a trustworthy brand and if you don’t have any bones about the design of it (like the colors I mean, nothing wrong about the shape or the operation), it’s a great choice. The adjustable alarms save you a lot of guess and check work too. Overall I’d recommend this meter because the next best thing is probably 50 bucks more in my experience.

straightforward meter. not really any bells and whistles but tpi is a solid company and this is a quality unit. easy to find leaks with the beeper.

Inexpensive, but effective at pinpointing gas leaks.

these are almost a commodity these days but for the price this unit has been more than adequate. just follow the beeps to your leak and wham bam thank you maam.

I dig TPI tools for my combustion season. The elephant in the room is that they are funky looking. I grant you that but if we look beyond appearances I’ve found that all their tools perform as well or better than competitors for a much lower price. This little gas detector has an adjustable alarm and I like the click wheel for sensitivity. Yeah it’s nothing earth shattering but it’s a solid tool at a price you can’t beat.

The thumb wheel makes adjusting the tic rate easy to you can pinpoint any leak. The bright green color is helpful so you don’t forget at the jobsite.

Like other reviews have said this is a no frills meter but it is well made and it has great senstivity for a very low cost. I don't think there's much competition for the ppm range in this price range

I don't think I've seen another meter with 10 ppm sensitivity at such a low price point. Barely over $100 and you get sensitivity of other models that cost over $200. That alone makes it worth the purchase for me

I try to buy local when i can and while i did buy this online, TPI is located here in Oregon! Thats pretty local if you ask me. As far as the instrument goes, it worked for finding my leak and it was a cinch.

It is very important to use these on every job you are tampering with lines that hold gases. Even the smallest leak can be hazaradous and an explosion waiting to happen. I dont know about you but i couldnt live with that if it happened to a customer of ours.
