The Calorific Value Tester for Building Materials is mainly composed of a constant temperature bomb calorimeter and a microcomputer system. Controlled by computer software, it is a multifunctional and automated calorimetric instrument capable of processing test data. This instrument is characterized by high measurement accuracy, easy operation, reliable performance, and elegant appearance. It is primarily used to determine the heat of combustion (calorific value) of combustible materials such as coal, petroleum, chemicals, food, wood, and explosives.
