1 Pcs K-Type Sensor Surface Temperature Probe High Temperature Thermocouple -50 to 500℃

Does the job definitely not for everyday use but very good for the price and pretty accurate

This does work well. I bough it to use with PEAKMETER K Type Thermometer I purchased at the same time. However, I was going to use it on plastic extrusion machinery running 700-800F and I have to keep it in contact with dies at those temps. It made me nervous how slow the meter was taking to settle at its reading and I didn’t want to keep the sensor in contact with such high heat for too long. I’ve used $200 units that read in a few seconds. After 15-20 seconds I stopped because I didn’t want to render it useless. It should work fine on engines, motors, etc. but it does work well.

pretty good for the value

The single thing going for this probe is its price. A probe from Fluke or Omega would be $100-$150 for something like this, and I paid $13. Is the quality the same? Not even close. The build quality and fit and finish are poor, and the metal clamp that protects the cable actually came off in the box. However, the screw went right back in and it was fine after that. Most importantly, the accuracy seems fine. When I compare the readings from a much more expensive probe, I'm generally within one degree. I bought this probe specifically because I have some applications that may damage the probe, and I didn't want to worry about wrecking an expensive probe. At the same time, I want something fairly accurate, and so far it seems to fit the bill nicely.

Compared it to a Cooper temp clamp and this thing was almost 20 degrees off. Used it for about 30 seconds then found the nearest trash can. Unless you’re trying to read 1000 degrees and a little variance doesn’t matter this thing is not worth getting.
