This instrument is a multifunctional calorimeter developed using a single-chip microcomputer, primarily used for determining the calorific value of solid and liquid combustibles such as coal, petroleum, food, wood, and other materials.

This instrument is a newly developed energy-saving analytical device by our company. A meticulously designed calculation program significantly enhances measurement accuracy. It features an LCD display with full Chinese language support, user-friendly operation, and achieves fully automated control of the measurement process, including automatic water filling, drainage, ignition, stirring, calculation, and printing of the calorific value of the measured substance. The experimental results are clear at a glance, making it an ideal testing equipment for enterprises and universities involved in the production and research of combustible materials.
