The measurement is taken by placing the apparatus against the exterior glass surface of the unit, and successively lowering the temperature of the measuring surface until the moisture vapour within the air space begins to condense on the lower interior glass surface in the form of dew or frost. The apparatus can be used in any orientation, the unit can be measured in a horizontal position or a vertical position by means of a simple vertical attachment.
