Thermal Tools for Circuits -- Workbench Wednesdays 20

Thermal Tools for Circuits

element14 Presents | Bald Engineer: James Lewis' VCP Profile | Workbench Wednesdays

Measuring the effectiveness of a heatsink or the thermal load of a CPU requires thermal test tools. In this episode, learn how an IR Thermometer and a Thermocouple could be used on an electronics workbench. Many multimeters (DMMs) include the ability to measure temperature with a K-type thermocouple. See examples of when each measurement could be used.

I was just looking at these yesterday. I saw the "guns" running from $10 to $100. If you're only using one occasionally, can you get away with something on the cheaper side? I saw the one you demoed was only $25 or so, so I'm thinking yes.

Thanks

I would say, Yes. Unless you're doing "real" work with one on a daily basis, something in the $25-30 range makes sense to me. They are very handy to have around and have, literally, saved my fingerprints a few times.

I was thinking about one because I have something called Raynaud's which makes my fingers get very cold, and I was wondering just how cold. Thanks for the advice!
