I have one of those IR temperature meters that I use for seeing how hot heat sinks and the like get. It works great when pointed at most tings. However, today I was measuring the temperature of a silver coloured metal shield which forms the top of a tube mixer. After a couple of hours it is quite warm to the touch yet the IR meter thinks it is only around 20 degrees Centigrade. I pinched the regular thermometer from the garden and place it on top of the mixer. It now reads 35 degrees but the IR meter still thinks it is 22 degrees. I have checked on a black surface (the top of the external power supply) and although that does not feel warm the IR reads it as 28 degrees so I think it is working. I am going to place a strip of black electrical tape on the top of the mixer shield and see what reading I get.
