High-precision microcomputer calorimeter calorific value detector for coal kcal laboratory equipment

Microcomputer automatic calorimeter is used to measure the calorific value of coal and combustible solid or viscous liquid substances such as petroleum, which meets the requirements of GB/T213-2008 "Method for Measuring the calorific value of coal".1. CRT display materials are selected to make the touch screen last longer. Covered with multi-layer composite film, it ensures the color distortion, reflectivity and clarity to reach the state, with sensitive sensing and high positioning accuracy. The infested area is up to 90% wear-resistant, and the service time can be as long as 10 years. Chinese characters are displayed without external computer. It can be operated directly and controlled by computer. Equipped with mouse operation to increase the use time of touch screen, Chinese menu operation interface, simple structure, intuitive and easy to learn, convenient operation, stable and reliable performance, and strong anti-interference ability by photoelectric isolation of inner and outer cylinders. Foam insulation technology is adopted, which is not affected by external temperature during the experiment.2. Automatically adjust the temperature of the inner and outer cylinders, reduce the cooling correction coefficient, and make the measurement result more accurate. Meet the requirements of GB/T213-2008 "The inner cylinder is about 1K higher than the outer cylinder at the end".3. Stainless steel vacuum inner cylinder. The mixing system adopts the original German motor.4. The test speed is fast, and the test period is ≤8min (fast method) ≤15min(GB/T213-2008).5. heat capacity stability <0.2% precision <0.1% temperature resolution 0.0001K6. This product has good performance and reliability even in harsh environment.7. Compact structure, beautiful appearance, simple installation and maintenance, and low failure rate. It is convenient for users to use the fault diagnosis function.8. Small size, large use of molds, high precision. The memory reserves are large, and the memory reaches 1000 pieces of data for users to query at any time. With temperature rise curve, it is convenient for users to estimate calorific value at any time.9. The repeatability and reproducibility of calorific value test are better than the requirements of GB/T212-2008. The results are accurate, and the cooling correction system, water circulation system and software automatic and error compensation system have the functions of large water storage capacity and good thermal stability of the outer cylinder at the same time.10. High degree of automation, automatic utilization of the water quantity in the built-in fixed container, automatic control of the temperature difference between the inner and outer barrels of the instrument, automatic water injection, no need to adjust the water temperature, just put the oxygen bomb into the barrel, and the instrument can automatically complete all the tests. Reasonable structure, excellent manufacture, reliable performance and low failure rate. Automatically complete the whole process of the test. .The fully automatic calorimeter adopts a single-chip microcomputer system to control the instrument to realize automatic water filling, automatic water temperature adjustment, automatic quantitative water, automatic stirring and automatic ignition.Temperature measuring range: 0℃-65℃Temperature measurement resolution: 0.0001℃Accuracy of calorific value test: better than 0.2% (benzoic acid)Power supply: AC 220v 10% 50hz.Quantitative error: ≤±1g Heat capacity: about 10450J/k.Test time: about 15min.
