Yes I would have used       pyrometer too.. I have my IR at 0.94e as default! Glad you are sorted..       C+              ------------------------------------       Here is a take on paint vs the oxide layer:       https://electronics.stackexchange.com/questions/333823/does-the-       aint-colour-matter-on-a-heat-sink       "Do not paint heat sinks. The layer of paint will act as an insulator       between the metal and the air, reducing its ability to dissipate heat.              Anodizing a heat sink is less of an issue. The anodization layer is much       thinner than paint (a few micrometers in aluminum, for instance), so it       presents a much lower thermal resistance than paint would."              I use black tape to optically measure the temperature of my walls and window       film, to compare them to interior walls and search for correctable heat       loss. For electronics and motors the IR thermometer and imager show patterns       of temperature rising and stabilizing, relative but not actual values, I       trust only a thermocouple in a well for that. Usually temperature difference       or rate of change are all I need to know, since the temperature that will       cause damage is often uncertain.              If accurate results are important I record the thermocouple data with a       PC-connected TP4000ZC multimeter calibrated to melting ice and boiling       water. The output file can be changed to .csv and imported to a spreadsheet       to correct observed offsets. This is for retired hobby use, to approximate       the professional lab instruments I had used at work.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
