TL1004 K-Type Sensor Probes Metal HeadProbe for K-Type Probe Thermocouple Sensor & Meter in Temperature Range from 0 to 500 °C

This thermocouple seems to work just fine. I used lots and lots of Omega thermocouples when I was working and this one seems to be as effective as those. I don't know about the calibration but it's probably close enough for my around-the-house and hobby needs. I'm using an old Keithley multimeter that has a TC input for my readout.

I use this for measuring temps in racing tires and found it to be as accurate and well made as the Fluke that someone decided to "procure" from my pit box! I have a thermal gun also, but the accuracy of measuring at specific locations of the tire is not very good with the thermal as it is with the contact thermocouple.

Economical. It reads a couple degrees off. In tolerance

Well made, and works well. My unit when used with a Testo K-Type adapter read temperatures that were off by about 1-2 degrees Fahrenheit when compared against my FLIR thermal imaging camera.

This probe (in conjunction with any of the multitude of compatible meters) makes it possible to measure the temperature of the rubber in a tyre.I am not a racer, but I wanted to find out how my tyres were wearing before they actually wore. Tyres wear because of friction with the road, and friction generates heat. If the tyres are getting hotter than necessary then they are wearing more than necessary.Typically as soon as I arrive home after a long drive I measure the temperature of the tread of each tyre near the inside, in the centre and near the outside. Ideally, all 12 readings should be very similar. If the inside and outside are higher than the centre then the tyre pressure is probably too low. If the centre is higher than the inside and outside then the tyre pressure is probably too high. If just the inside front temperatures are higher than all the other temperatures then there is probably a problem with toe-in. If the inside is high, the outside low, and the centre in between, then suspect camber.Readings stabilise within a few seconds, so it is possible to take all 12 measurements before the tyres cool off significantly. The nice thing about this kind of pyrometer (compared to an infrared thermometer) is that it measures the temperature under the surface of the tread, which retains its temperature much longer than the surface.This pyrometer has a fixed pin that penetrates about 5mm into the rubber. I have seen others in which the penetration depth is adjustable, but 5mm seems a good choice (deep enough to get away from surface temperature anomalies, but not so deep that it is hard to insert or in danger of puncturing the tyre).I have only had mine for a few days, so I can't speak for durability yet, but so far I am very happy.

I bought this two years ago to use in my smoker. I can't say for hi-temp applications but in my experience cooking at a maximum of 500° F (260° C) I have had no issues with this probe. Braiding is in-tact, no fraying at all around the probe end. The connector side, however has frayed multiple times and needed to cut back and re-install to the plug which is not a big deal since the plug is servicable. Broke one of my first probe wires from closing in the smoker door and never had another issue since installing the grommets. Came back on here to buy a second one as a back-up. Would definitely recommend.

Besides the response time being pretty slow, the one I received was not accurate. I connected it to an Inkbird temperature controller to test the temp of an electric oven. It worked erratically. I put it in boiling waster to test it and it indicated 97.5 deg C (207.5 F) at close to sea level. I compared it to a more expensive TC, and it indicated 99.6 deg C (211.28 F), an acceptable margin of error. I would have used the one I had, but it isn't heat resistant. Looks like it is going in the trash since I missed the return window.

Bought this to replace a worn out set that came with my multimeter years ago. Will work with any meter that accepts k-type thermocouples. Seems to be very accurate and repeatable.
