The KR-5000D calorimeter is a multi-functional calorimeter developed by a single-chip microcomputer. It is mainly used for the determination of calorific value of solid and liquid combustibles such as coal, petroleum, food, wood, explosives and so on.
KR-5000D High-precision Fully Automatic Calorimeter (Touch Screen Cooling Version with cooling system)
The KR-5000D high-precision fully automatic calorimeter adopts compressor refrigeration and inner barrel heating, equipped with an intelligent constant temperature system, which has better testing accuracy and stability. It is used to measure the heat generation of materials such as coal, petroleum, gangue, building materials, biomass fuels, etc., and meets the requirements of GB/T213-2008 "Method for Determination of Heat Generation of Coal", ASTM D240, ASTM D5865. High degree of automation, automatic use of built-in constant volume device to determine the water volume of the inner bucket, automatic control of the temperature difference between the inner and outer buckets of the instrument, and automatic completion of the entire test process. This machine maintains all the functions of the microcomputer system, and during the testing process, the temperature curve is clear at a glance. The experimental results are automatically displayed, printed, and a large amount of historical data is automatically saved, which can be viewed and printed at any time.
