SP H-B DURAC General Purpose Lab Thermometer Total Immersion Glass Liquid Thermometer for Laboratories, Universities, Food and Beverage Processing, -20 to 150 Degrees Celsius

Arrived on time. Works as described.

It came damaged and when I tried to get a return and a replacement, it said the item was not eligible for return So if I were you, I would not buy this

We started homeschooling our kids last year. This is a good product that does the job for science projects.

First one I had was great! Broke it accidentally, so I ordered a second one. The second one arrived broken… Without the broken parts inside the tube! According to Amazon, it was not eligible for a refund or replacement! Spent quality time trying to figure out how to get my money back. It’s horrible end up in a matrix that you cannot get out of because of pre-incline questions that get you nowhere such as “have you tried to re-calibrate it“ “did you replace the batteries“ finally got a refund by talking to a representative.

I was looking for the 150 C upper range and it arrived with a 110 C max. Useless for my application.

Worked great for my chemistry class

Works like you'd expect, which is perfect. My example reads +0.5C.

It's good but not completely accurate. It's about 4 degrees off
