FIELD: physics; measurements.
SUBSTANCE: invention pertains to measuring techniques. The upper part of the calorimeter chambers is hermitically fixed in the openings of a disc, while the lower part of the chambers is put in the inner cavity of a thermostat. For this, the wall of the thermostat adjacent to the disc is made with openings, the diameter of which is larger than the diameter of the chambers. The thermostat is in thermal contact with the lower surface of the disc and its temperature is kept at a constant value lower than the temperature of the chambers using a regulating system.
EFFECT: lowering threshold of sensitivity of the calorimeter and increased reproducibility of results of measurements.
