XDLR-8A microcomputer fully automatic calorimeter

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". Strong, 1. The use of PCI card to COM port displays its uniqueness and arbitrariness in the control quantity of the calorimeter host. 2. The entire experimental process does not require many manual operations such as weighing water and adjusting water temperature, making the operation simple and convenient. The appearance is beautiful, the materials are carefully selected, the production is excellent, the structure is reasonable, and the failure rate is low. 4. Adopt efficient magnetic stirring method to facilitate rapid convection of water in the inner bucket, ensuring thorough mixing and stable testing during the main period. 5 adopts advanced serial port technology to adapt to the new development of computer technology and achieve multi control for one machine. Coal testing equipment, coal quality analysis instruments, sulfur meters, coal detection instruments Technical indicators and parameters Temperature measurement range: 5-40 ℃ Temperature resolution: 0.0001k Precision: 0.1% Thermal capacity: about 10450J/K Outer water tank capacity: about 40L Inner water tank capacity: about 2.1L Power supply voltage: AC220V 50Hz External dimensions (mm): 385x365x385 Host weight: about 40kg Single sample testing time: about 15 minutes

Adopting a unique cooling correction system, water circulation system, and software automatic error correction system, with a large outer cylinder capacity, the instrument performance is guaranteed to be stable for a long time. Adopting unique foam insulation technology, the experimental process is not affected by external temperature Customized cooling capacity can be determined based on the previous heat generation, balancing the circulating water system to maintain a relatively constant water temperature and reduce environmental impact. This perfectly solves the common problem of the desktop automatic calorimeter being unable to conduct continuous experiments due to the outer bucket water temperature exceeding 1.5 ℃ after 10 consecutive experiments (the national standard requires that the outer bucket and room temperature during the experiment should not exceed 1.5 ℃), making the experimental results more accurate and truly leveraging the advantages of the automatic calorimeter. The use of inner and outer tube photoelectric isolation has strong anti-interference ability. The unique and arbitrary control quantity of the calorimeter host is displayed by the conversion of PCI card to COM port. The entire experimental process does not require many manual operations such as weighing water and adjusting water temperature, making the operation simple and convenient. The appearance is beautiful, the materials are carefully selected, the production is excellent, the structure is reasonable, and the failure rate is low. 4.
