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

I needed to measure a refrigerant pipe that was in an awkward spot inside a mini split outdoor unit. This was available for overnight delivery so I thought I'd give it a try. I was surprised to find that it matched my Klein clamp-on thermocouple exactly when testing the same pipe side by side. This did the job and helped me confirm there was no obstruction in the refrigerant line strainer on my unit. It now lives in my HVAC toolbox!

Works great with my fluke meter. Had to buy an adapter also but still way cheaper then buying a fluke one.

We have attached individual K type thin wire sensors to key hot water pipes in our building; we use an OMEGA hand held meter. The sensors are seated firmly with insulated tape and are the most accurate (matches our FLUKE) we have found. . The new OMEGA touch sensor must remain in contact for about 30 seconds and is typically 5 degrees less than the permanent one, but accurate enough knowing that difference.

Solid, well made, accurate, easy to use, very inexpensive.

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.
