I just bought a rolson infrared thermometer to measure my Primary flow and return as well as both ends of the rads to optimise my system.
Problem is it is giving me duff readings. The instructions say that this can happen if the surfaces are either transluscend or shiny. The remedy is apparently to place masking tape ipon the surface of say the chrome 15mm copper and read again once masking tape has reached temperature.
I tried this but i firstly don't think a piece of masking tape will ever get as hot as the copper and therefor i'm a bit lost with this thing.
Anyone out there got one. If so what do i do?
