Multi-functional Calorimeter for Coal, Petroleum, Food Calorific Value Determination
Application:
The KR50 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. This instrument is a new energy-saving analytical instrument newly developed by our company. The calculation program is carefully prepared to greatly improve the measurement accuracy. It adopts liquid crystal display, which is easy to operate. It can achieve all automatic control measurement process, automatic watering and drainage. , automatic ignition, stirring, calculation, printing the calorific value of the measured substance, and display the experimental results, is an ideal laboratory equipment for the production and research of combustible materials enterprises and colleges and universities research and military departments.
Technical characteristics
1. This machine is made up of high-grade single-chip microcomputer, with simple structure, reliable performance and strong anti-interference ability.
2. Can automatically add water, drainage, mixing, ignition, temperature, calculation, calibration, printing, experimental process to achieve full automation, avoiding human error, accuracy and precision greatly improved.
3. The experimental automatic cooling correction, the requirements for the ambient temperature is relaxed, while improving the accuracy of the experiment, but also to ensure the stability of the instrument for long-term operation.
4. After the experiment, the high and low calorific values can be automatically converted and printed, which is more in line with the general routine experiment.
5. Easy to operate.
