Review on Thomas Traceable Flip Stick Thermometer Degree by Tyler Markham

Stronger than I thought. I use it in concrete field tests and it gets dropped and bumped a lot, but it still works (although I try NOT to get it too wet). I buy another because I need to keep a calibrated device and this is the easiest way. Also, it's displayed in 1-degree increments (tenths, actually), so essentially conforms to ASTM C1064 standards (there's no such thing as 'ASTM approved'), and the display is quite large, so if you're standing people have around and watch your results, that's great. And thanks to the hold function, I don't have to remember the temperature while I run other tests. You can also stick it into the concrete at an angle and hook the little lip of the body over the rim of the bucket/container, all you have to do is wipe the stick. It's definitely way better and way more durable than any other joystick (dial or digital).
