Our company develops and produces calorimeter, sulfur analyzer, industrial analytical instrument, coal sampling and preparation equipmentFast intelligent sulfur analyzerCalcium iron analyzer, carbon hydrogen analyzer and other products have been widely used in industries such as coal, chemical, power, metallurgy, environmental protection, geological exploration, etc. throughout the country.

The microcomputer fully automatic calorimeter is used to determine the calorific value of combustible solid or viscous liquid substances such as coal and petroleum, as well as the explosive energy of explosives, in accordance with the requirements of GB/T213-2008 "Method for determination of calorific value of coal".

1. Adopting a compressor refrigeration method, automatically adjusting the temperature of the inner and outer cylinders, reducing the cooling correction factor, and ensuring accurate measurement results. Adopting a refrigeration and temperature control system to keep the temperature rise and fall at 0 during the experimental process. Ensuring the stability and accuracy of the experimental results. The semiconductor refrigeration type water circulation system can customize the cooling capacity based on the previous heat generation, balance the circulating water system, keep the water temperature relatively constant, reduce environmental impact, and solve the common problem of the external bucket water temperature exceeding 1.5 ℃ above room temperature after 4-5 consecutive experiments in the past (requiring the external bucket temperature and room temperature to not exceed 1.5 ℃ during the experiment), making the experimental results accurate and leveraging the advantages of the fully automatic calorimeter

2. Stainless steel vacuum inner cylinder. The mixing system uses an electric motor.

3. Thermal capacity stability<0.2% accuracy<0.1% temperature resolution 0.0001K, this product has good performance and accuracy even in harsh environments. Compact structure, beautiful appearance, easy installation and maintenance, low failure rate. Compact in size, extensively manufactured using molds, with high accuracy. The repeatability and reproducibility of coal calorific value testing meet the requirements of GB/T212-2008.

4. High degree of automation, automatic utilization of the water volume in the built-in fixed container, automatic control of the temperature difference between the inner and outer buckets of the instrument, and automatic completion of the entire experimental process. Using the Windows XP operating system, multiple controls are implemented on one machine, with no impact on each other's testing and high software stability. The data processing function is rich, and users can easily query historical experimental data, current day data, parallel sample data, etc., meeting the requirement of GB/T213-2008 that "the inner cylinder is about 1K higher than the outer cylinder at the endpoint".

5. The microcomputer fully automatic calorimeter maintains all the functions of the microcomputer system and can run general software for other transaction processing. At the same time, starting the calorimeter measurement system can automatically calibrate the energy equivalent (heat capacity) and measure the heat generation of the calorimeter system. Input data such as sulfur, moisture, hydrogen, etc. to convert and print out data such as cylinder heat generation, high-level heat generation, low-level heat generation, etc.

6. The internal cylinder of the calorimeter device adopts electric stirring with sheet-like blades, and the external cylinder adopts submersible electric stirring to ensure uniform and convenient stirring. The instrument adopts a fused cotton thread ignition method.

7. The microcomputer calorimeter is operated on Winsows98 and above operating systems, with Chinese character prompts and human-computer interaction throughout the entire process, ready to learn and use. Follow the prompts to complete the experiment
