Hi Guys,

I recently bought a cheap but seemingly accurate dual channel digital thermometer on EBay and I have a question for you all.

What are you guys all using to measure temps and how do you actually connect the sensors to various points to get accurate readings? This is obviously a critical piece in determining system performance.

With the thermometer I bought, I'm having issues getting repeatable and reliable temp measurements. My problem seems to be attaching the thermocouples to the copper lines in such a way that it reads accurate temps. This unit just has thermocouples on the end of the leads that run to the meter. I assume that clamp-on type thermocouples would fix my problem, but I don't want to spend a bunch of money for as little as I'll use this.

Suggestions?
