I \u201cstole\u201d the trustworthy Omegaette HH306A temperature meter from my day job testing station and have been using to measure vaping cell temperature during testing. It\u2019s time to move it back permanently. It\u2019s just too annoying moving it back and forth when needed. The other meters I have can be used but aren\u2019t quite as accurate.<\/p>\n

This gave me an opportunity to upgrade though to the Fluke 52 II, an incredible two channel meter. Especially when paired with tight tolerance thermocouples (temperature sensors) and an extra NIST-traceable calibration done before the Fluke was shipped to me. In the photo you can see two different sensors showing the same 26.8\u00b0C ambient temperature…just what I want to see.<\/p>\n

You can see one of the temperature sensors on the upper right, with its \u201cbead\u201d tip circled in red. It\u2019s this tiny tip that makes these thermocouples so great for measuring cell temperature. It responds very quickly to the changing cell temperature, it thermally couples itself well to the cell using a dot of thermal paste or thermal epoxy, and it\u2019s easy to isolate from the effects of cooler ambient air using Kapton tape to mount it to the bare cell (wrap removed).<\/p>\n

Exciting stuff? No, not really. \ud83d\ude42<\/p>\n

Just another step to ensure that the results I give you are accurate.<\/p>\n
