uxcell K Type 50x5mm 500C Probe Thermocouple Temperature Sensor Cable - 9.8ft (3 Meters) Review

Bought 2 probes for coffee roasting. The price is great. The accuracy is not perfect. I switched sensors between thermometers and they showed +-3%. Note: 8mm x 1.25mm thread if that helps.

Received quickly, seems to work well, the only thing that confuses me is that the woven lining seems a little "soft". It looks like there is no inner insulating sleeve to protect the thermocouple wires. It works well in my homemade heat chamber.

thermocouple failed after a few months of use. The meter reported an "open circuit". I fiddled with it a bit and found that pushing the cable into the spiral strain relief works temporarily. So I opened it up and saw that the crimp where the wire enters the probe tube was so hard that it practically destroyed one of the wires, which then broke internally a few months later. Avoid this product if you intend to use it more than a few times.
