I will check the model number of mine when I get home

The one I have does LN2 temps no problem

But for 50 bucks the Fluke looks good

[Patch]

Maybe out o' date by a handful of years.

1) Older Fluke 52 from fleabay. Most reliable by far, but slow refresh rate - about every 2-3 seconds if I recall. 2 seconds doesn't seem like much, but it's an eternity when finely titrating temps at the razor edge around cold bug territory. Two probes were nice, but of limited use since I had to manually toggle between them on the screen with my older model.

2) Used UEI DT200 from fleabay. Two probes with both temps on the main screen. Fastest refresh rate - almost real-time temp changes, though that's probably why it ran through battery 20 times faster than Fluke. My favorite therm, but had to be careful to change the battery before it died or it would lose calibration.

3) Little yellow generic guys from China. $29 used. Mixture of speed and accuracy. Tended to wig out frequently and need reboot.

4) Generic therm from Elano. Not bad, but didn't go below -100 very well.
