T-PRO K-Type Thermocouple Wire for Very High Temperature(0-1000℃) Fiberglass (1M Wire)

I needed to calibrate the porcelain furnaces at the dental lab I work at...the thermocouple that came with the digital thermometer was only good up to 1200 degrees and I needed to have the ability to get to 1750 and the 2200 limit on this thermocouple was more than adequate...the fiberglass insulator barely changed color's in the heat looks like I'll be able to use it for a long time... that's good because we have 6 furnaces to keep accurate....10 degrees off makes a big difference in the look of the porcelain teeth...

I got tired of dealing with flaky cheap thermocouples and decided to spend a little more on this model. I'm glad I did as it solved some of my intermittent reading issues. The wires are are much thicker gauge than the cheap stuff and the weld at the end looks nice and solid. Both the hot end and the connector end are nicely finished and the plug has solid pins. The only caution I would give is that the cable is relatively stiff due to the wire gauge and in certain applications that could be an issue.

Unreliable and doesn't seat snugly. If you manipulate the wire at all you can get the reading to change. Whether this is due to there being a break somewhere in the middle of the probe or because the prongs are moving around in the sockets is unclear. Tried with both a Fluke and Amprobe thermometer. Because of the instability the probe is basically useless.

I use this in my smoker, bbq, oven and forge. works like a champ in all of them. its a game changer when you actually know the temp. or at least within 20 degrees of it.

Great quality thermocouple. But I've experienced some strangeness, both my Keithley DMM6500 and two Flir handhelds agree in temp with this thermocouple, but my Siglent SDM3055 reads 10 degrees low. However if I use the cheap yellow thermo that came with my handhelds all of them including the Siglent read bang on the same temp. I don't get it, even at room temp the Siglent will read 10 low with this product for some reason.
