Digi-Sense Calibrated Long Stem Digital Pocket Thermometer, 8" L, -58 to 302F/-50 to 150C

Great delivery pod his was as described.

I use these to calibrate data loggers. The NIST certs are legit and include the uncertainty data. I buy a new one each year, but can safely say that the old ones still give accurate readings. BTW, my sous vide makes a great cal bath. And Boveda bags are adequate RH cals.

This thing has a nice, long battery life. I have it on 24/7 and stuck in the top probe port of a lab incubator, so I can keep some chemicals dissolved in water that love to crash out at room temperature, but are happy above 30 C. So far it's worked quite well for this purpose. The display is mostly easy to read (up close anyway), though it is rotated 90 degrees if you have it sticking into something perpendicular to the ground. All in all, pretty happy with it for my purposes, but I haven't come close to pushing this thing to its limits.

Works great and easy to verify calibration. Long stem but be careful if used around alot of steam. Will not work great on the digital display after some use.

I used these thermometers for years and they were reliable back then, but something has clearly changed. After they became unavailable for a while, I was glad to see them listed again and bought four. Within one day, one of them failed completely — the display went black. Worse, three days later we lost a batch of product because the other thermometers were all giving the same incorrect readings. We double-checked with a mercury thermometer, and every one of them was off by the same amount. That kind of systemic error is unacceptable, especially for a product sold with a certificate of calibration and traceability. Clearly, something in their quality-control or calibration process has slipped. I would never buy these again — the cost of the product we lost far outweighs any savings or convenience. One star across the board.
