What do you use to mesaure temps?

I am building my first dry ice system and was wondering what meters/probes you guys use? Where do you normally mounts your probes?

Well, ou need some normal thermometers with measure bandwith between +xx°C and -200°C, if you want to bench with LN2, DICE will max be around -75°C.
The heat sensor is usually put here

I use a DT 301 thermometer with a k type probe for my measuring needs.

EXTECH 421502 K/J thermometer

got it and a 12" tall, 2" dia copper pipe DICE pot for my H50 because the prev. owner spilled acetone on the thermometer, still functions and is easily readable, so it was a great way to spend the money!

UEI DT302 here. Very nice refresh rate, dual input and accurate with both probes inserted.

I use overclocked Fluke 51 II thermometers (to 54II) and Fluke 87V. Waiting some arrival of new meter also.
