A RADIATION CALORIMETER FOR THE ABSOLUTE MEASUREMENT OF RADIATION INTENSITIES BETWEEN 0.4 AND 12.5 WATTS/CM2

Lawson, D.I. and McGuire, J.H., 1953. A RADIATION CALORIMETER FOR THE ABSOLUTE MEASUREMENT OF RADIATION INTENSITIES BETWEEN 0.4 AND 12.5 WATTS/CM2. Fire Research Notes 37


ABSTRACT

A continuous flow radiation calorimeter is described in which a radiation flux produces a temperature difference, detected by a thermistor bridge, between the inlet and outlet of the water circuit. The rate of flow of water through the calorimeter is self-stabilizing. The radiation intensity is measured by replacing the radiant heating by an equivalent rate of electrical heating.
