Klein Tools ET10 Magnetic Digital Pocket Thermometer, HVAC Instant Read Thermometer with Backlit Display, Wide Measurement Range, Fahrenheit and Celsius

The Klein Tools ET10 is a pocket-sized, magnetic digital thermometer, ideal for HVAC professionals or technicians looking for a compact, convenient, and affordable tool.

This thing is super handy, it dose however lie about the temperature it can read. If you need something that reads over 160 degreese f, then buy another item. The body will melt with exposed temps over 200.

Bueno

magnet doesnt hold if mounted horizontally. barely stays attached if mounted vertically. stronger magnets would have fixed this issue. reads temps ok. dont buy just because it has a magnet

This bad boy is what you need. It ticks up and down sort of slow but it is accurate and magnetized in a clever way. Also orange so I can remember to get it easier.Still haven't lost my first one yet.

I use only Klein tools and this works great. I am a facilities manager and this tool is accurate and well built.

20-year HVAC tech here....I love Klein tools, nine times out of 10 they are great. This is very accurate which is important, But the magnet is pure junk. It does not stick to ductwork, or system cabinets etc because the magnets are just too weak not a terribly difficult fix, I bought a package of neodymium magnets better small enough, and rectangle shaped to glue in place, over where the weak magnets are. Just a pain to have to do that, I sought out the magnetic feature on purpose.

Really handy for checking air and liquid temperatures. The magnet is great. Backlight is bright . Auto turns off as well
