DEVICE FOR MEASURING HEAT CAPACITY OF MATERIALS Russian patent published in 2018 - IPC G01N25/20 

FIELD: test technology.

SUBSTANCE: invention relates to thermal tests, namely to devices for determining the heat capacity of materials, and can be used to determine their thermal properties. Device is proposed for measuring the heat capacity of materials, which contains two calorimetric cells placed inside a shell filled with heat-insulating material, equipped with temperature meters, electric heaters and means of supplying power to them. In this case, the means for supplying power to the heaters is made in the form of a capacitor connected to the mains via a rectifier, to which a second capacitor equipped with a voltmeter is connected in parallel via a computer-controlled relay through a computer-controlled relay connected to the heaters of both calorimetric cells.

EFFECT: increased determination accuracy of the required parameter.
