Hi all,
We're doing some thermal calculations for a some existing equipment and as it's outside need to quantify the solar gain. This obviously depends on the absorption coefficient, which in turn depends on colour, finish, cleanliness etc.
Is anyone able to recommend / point us in the direction of a portable device that could measure the absorption coefficient in the field, or perhaps suggest a method for getting a reasonable estimate?
We don't need to be accurate to the nth degree, just enough to quantify where we lie between "white" or "light grey" (as the standards we're using refer to them).
