I knew I could dig a sense or humour out of you....
BTW - I found a 'laser' temperature measuring device today and experimented. But unfortunately have found the measuring technique fraught with difficulties and error.
Firstly the emissivity of materials plays havoc with the accuracy and although the 'laser' measuring device sounds ideal, of course it has a multitude of problems. It's 'real' IR measuring beam is subjective, distance, obstruction and a multitude of effects cause inaccurate results and so even using a 'branded' unit, I still failed to attain an accurate and stable reading. Better off mounting several thermocouples with glass tape to be honest, apart from the revolving bms itself of course!
I'm still not 'taught' yet, I have to say, or understand why we all have such differing results, but I do believe the world is round so at least we all agree on something - I think!?
Mind you - we also have seem to have attracted a reasonable following as shown by the number of views -but just wish a couple of others would join in.
