Great for small applications
40awg works great for my small devices —- allowing me to get right to the spot I want to measure.

Nice Product
I purchased a package of 5 thermocouples. They arrived well packaged and, for someone who doesn't work w/thermocouples, the workmanship and insulation were very nice. I would definitely purchase this product from Omega again.

Excellent TC's
Excellent thermocouples, durable and directly integrate-able into all of our multiplexer systems. The connectors (separate purchase) make quick work of the bare wire for our handheld probes. Easy.

What is the temperature range for 5TC-TT-T-20-72? Can it measure at -80℃? what is the maximum temperature? Then is this made up from special limit of error wire?
Thank you for your inquiry Lee1. The process temperature range of 5TC-TT-T-20-72 is 0 to 260 C (32 to 500 F) and this thermocouple is made from special limit of error (SLE) wire. It could measure -80 C but the accuracy for all the SLE thermocouples is not guaranteed for measurements below 0 C since it is non linear below 0 C.

What is the diameter of the thermocouple 5TC-TT-J-40-36? Can it be used at temperatures up to 500 °C? At what temperature does the insulation start to melt for this thermocouple?
Thank you for your inquiry Moe1. The size of the cross section of 5TC-TT-J-40-36 is 0.4 x 0.7 mm (0.017" x 0.026"). You cannot use 5TC-TT-J-40-36 at temperatures up to 500 °C since it is only rated for temperatures up to 260 C and will start to melt if used in temperatures over 260 C.

What is the percentage uncertainty for 5TC-TT-KI-40-1M? I am working in a temperature range of 15-60 degrees, is the uncertainty 0.4%, so 0.06-0.24 C?
Thank you for the inquiry. We do not provide uncertainty numbers for this series. Accuracy spec follows ANSI special limits of error; +/- 0.4% of reading or 1.1 C whichever is greater.

Are you able to cut the lead half of the wires on these? i don't want to trim them and cause a short.
Thank you for your inquiry. You can cut the leads as much as you need to.
