ASTM D 240 GB/T213-2008 Oxygen Bomb Calorimeter TP-1A+

Main characteristics and scope

The instrument is designed and made according to GB/T213-2008 Method for the determination of the calorific value of coal, GB/T384-1988 Method for the determination of the heat value of petroleum products and Calibration and Inspection Regulation of People’s Republic of China JJG672-2001 Oxygen Bomb Calorimeter.

The instrument adopts high precision temperature sensor and high-power A/D converter, and uses single chip microprocessor to form an intelligent temperature data collection and transfer system. It uses microcomputer to form an automatic, convenient, rapid, and intelligent instrument. If the user operates the instrument carefully and input all kinds of parameters correctly, the desired measurement data will be getted. The instrument can be widely used to determine the calorific value of materials such as coal, oil, coke, paraffin and other combustible materials etc. It is an ideal option of the thermoelectricity, metallurgical, cement, chemical industries, scientific research institutes, college and universities.
