Yeeco + K Type Thermocouple 0~1300℃ Temperature Thermocouple Sensor Temperature detector Temperature Gauge

The probe is well made with a nice strain relief/handle.

I'm using this, hooked to a "Leaton Digital Thermocouple Thermometer Dual-channel LCD Backlight Temperature Meter " to measure the internal temperature inside my propane forge. It's giving me what I believe is a much more accurate temperature reading than the IR thermometer I had previously used. The difference between these two methods had been as much as 500ºF.. I only have 1" of the tip inside the forge, and I added a 1x1/4x6" piece of aluminum as a heat sink between the nuts, so there are zero issues with the plastic end melting or even getting warm. YMMV. I've just used it a few times so we'll see how long the problem lasts.

Worked fine but absolutely not good to 1300. The whole thing turned crispy black and fell apart with one use up to 1150C.

I decided to give this little probe a torture test right out of the box to see if it would hold up. First, I applied a propane flame from a blowtorch directly to the stainless steel probe. It seemed to be sinking heat away from the tip too rapidly, and it only reached about 950°C. In a proper kiln or furnace where more of the tip is exposed to high temperatures, this shouldn't be a problem.Next, I pulled the sensor out of the probe and gave it a hot supper with the torch. It maxed out at about 1090°C, with the sensor and some of the wire sleeve glowing bright orange. Once it had cooled to about 450°C, I dunked the entire probe into cool water. Amazingly, the reading stayed accurate, and once I dried it off, it settled back down to less than 1°C above the reading from a standard thermocouple. I wouldn't expect it to stand up to this sort of treatment repeatedly, but it's good to know that it can handle it.Tip: if you need to connect it to a thermometer with a K-type jack, you can just cut off one of the prongs from each of the spade connectors and insert them into the jack. Make sure the polarity is correct; if the temperature reading goes down when heat is applied to the probe (and vice versa), flip the connections around.

Great value, but not good for accurate kiln use. It reads a little low over 2000F or so; which I think is due to the bead being covered by the sleeve. Good enough for low temps or something like a forge where +/- 25F doesn't matter as much.Also, I drilled the hole the same size as the probe and pushed it through about 1.5" of soft firebrick insulation. at 2300F the back end of the probe was cool to the touch. As long as you drill the hole properly you shouldn't worry about the plastic melting.

So far I've pushed it to 1000°C and it's holding up great. It really made a difference being able to get a temperature reading for my melts instead of just going by eye.

Doesn't work at all. Temperature reads backwards.Temperature is wacky.Edit: Works but is not standard coloring. The temperature is not on point, but is close enough for me. it is 7C off.Still not satisfied.

Great for the price.
