Performance characteristics
1. Heat capacity of automatic calorimeter
2. By inputting sulfur, moisture, hydrogen and other data, the calorific value of cartridge barrel, high calorific value, low calorific value and other data can be converted and printed.
3. It adopts the mixing motor imported from Japan, with stable mixing speed, reliable performance and strong anti-interference ability. Realize automatic water filling, automatic water temperature regulation, automatic quantitative water, automatic mixing, automatic ignition, reduce human error.
4. The calorimeter supports two ignition modes, i.e. ignition wire and cotton thread
5. There is a water level indicator line on the case shell, which can observe whether the inner cylinder is short of water at any time.
6. The ignition voltage and current can be observed outside the chassis at any time.
7. The original cooling correction model ensures the accuracy and reliability of the test results of high and low calorific value samples.
8. Stainless steel vacuum inner cylinder, large capacity outer cylinder water tank, refrigeration unit, stable heat capacity, suitable for long-time continuous sampling.
9. Advanced compressor refrigeration technology, completely free from the influence of environmental temperature changes, to ensure that the temperature difference between the inner and outer cylinders of the instrument meets the requirements of the national standard.
10. High degree of automation, automatic use of built-in fixed container bucket water, automatic control of temperature difference inside and outside the instrument bucket, automatic completion of the whole process of the test. It can be connected with electronic balance.
11. Unique cartridge, strong compression, shorten the main period of time. Real time monitoring of laboratory environment temperature and automatic prompt of out of tolerance results.
12. Automatic transmission of sample coding and weight information; backup and upload of test data; tamper proof of experimental data.
13. It can realize login authority management, rich data processing functions, and users can easily query historical test data, data of the day, parallel sample data, etc.
14. The product has good performance and reliability even in severe environment.
15. Compact structure, beautiful appearance, easy installation and maintenance, low failure rate.
16. The repeatability and reproducibility of calorific value test are better than GB / t212-2003.
17. Windows 7 operating system is adopted to realize multi control of one computer, and the software runs stably.

Microcomputer automatic calorimeter is mainly suitable for the determination of the calorific value of solid or liquid combustible substances such as coal, garbage, biomass fuel, petroleum, chemical industry, food, wood and other industries or departments, such as power, coal, paper making, petrochemical, cement, agriculture and animal husbandry, medicine, scientific research, teaching, etc. Complying with GB/T384 "Calorific Value Measurement of Petroleum Products" standard and GB/T 213-2008 "Calorific Value Measurement of Coal" and ISO1716 "Fire Reaction Test of Building Products - Calorific Value Measurement of Combustion" and GB/T 14402-2007 "Measurement of Combustion Performance and Calorific Value of Building Materials and Products"
