Fairly accurate temp readings, calibrated using ice bath

Starcraft2WOOT—August 8, 2025✓ Verified purchase

I wanted to see how accurate this digital thermometer was so i calibrated using a ice bath. One of the digital thermometer measured 33.2 F (assuming 32 F for the ice bath). This is fairly accurate since it is +/- 1 off. The other thermometer measured a bit higher (33.7) so they are not the same but close. My el cheapo analog thermometer from APi is more accurate in terms of the ice bath at 32F. But all good since it is within tolerance. Read more

Crazy readings, added these to my collection.

Gary—July 18, 2025✓ Verified purchase

These show different readings from all my digital heater so I run 5 and get an average 2 digital, the heater itself and two manual thermometers. I have Trust issues thinking one or more have been made by you know. Read more

Accurate But Didn’t Last

Elizabeth E. Lombard—March 8, 2026✓ Verified purchase

I have 4 of these but they all ended up with a blank screen. No, not the batteries. When I first got them they worked. Then they didn’t. But when they did they were spot on accurate. Read more
