Abstract

A low-cost water bath temperature control device, and an apparatus designed to monitor temperature variation from a null point both inside a precision calorimeter and in the surrounding bath, are described. Bath control to better than +or-0.002K in the 280-350K region can be achieved. Temperature variations in ranges between +or-2K and +or-0.02K can be measured to better than 5*10-2K and 5*10-4K respectively.
