Our company develops and produces calorimeter, sulfur analyzer, industrial analytical instrument, coal sampling and preparation equipmentMicrocomputer ash melting point testerCalcium 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 coal, the calorific value of combustible solid or viscous liquid substances such as petroleum, and the explosive energy of explosives, in accordance with the requirements of GB/T213-2008 "Method for determination of calorific value of coal".

1. Use CRT display materials to make the touch screen durable. Multi layer composite film coverage ensures optimal color distortion, reflectivity, and clarity, with sensitive sensing and up to 90% wear resistance in effective areas. It can display Chinese characters for up to 10 years without the need for an external computer. It can be operated directly or controlled by a computer. Equipped with mouse operation, increasing the usage time of the touch screen, a Chinese menu style operation interface, simple structure, intuitive and easy to learn, convenient operation, stable and reliable performance, and strong anti-interference ability by adopting inner and outer tube photoelectric isolation. Adopting foam insulation technology, the experimental process is not affected by external temperature.

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

3. Fast testing speed, testing cycle ≤ 8min (rapid method) ≤ 15min (GB/T213-2003).

4. Thermal capacity stability<0.2% accuracy<0.1% temperature resolution 0.0001K

5. This product has excellent performance and reliability even when operating in harsh environments.

6. Compact structure, beautiful appearance, easy installation and maintenance, low failure rate. Adopting fault diagnosis function to facilitate user use.

7. Small in size, extensively manufactured using molds, with high accuracy. The memory storage capacity is large, with up to 1000 pieces of data available for users to easily query at any time. Equipped with a temperature rise curve, it is convenient for users to estimate the calorific value at any time.

The repeatability and reproducibility of the heat generation test meet the requirements of GB/T212-2003. The results are accurate, and the cooling correction system, water circulation system, software automatic, and error compensation system are adopted, which also have the functions of large external cylinder water storage capacity and good thermal stability.

9. 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, automatic water injection, no need to adjust the water temperature, just install an oxygen bomb into the bucket, and the instrument can automatically complete all tests. Reasonable structure, excellent production, reliable performance, and low failure rate. Automatically complete the entire experimental process. .

The fully automatic calorimeter uses a microcontroller system to control the instrument to achieve automatic water filling, automatic water temperature adjustment, automatic water metering, automatic stirring, and automatic ignition.
