XDLR-2000A fully automatic touch screen multifunctional calorimeter

1. Using ARM as the main control chip and a 7-inch true color touch LCD screen to achieve simpler and more direct human-computer interaction. 2. Adopting a modular 24 bit AD temperature acquisition circuit ensures a temperature measurement stability of one ten thousandth bit. 3. By utilizing the data processing capabilities of computers, querying and printing historical data has become simple and easy, providing possibilities for future device networking and data sharing. 4. It has the vast majority of functions and unparalleled reliability of a microcomputer calorimeter in the previous personal computer+controller mode. 5. Real time cooling calibration, with relaxed requirements for environmental temperature, improves experimental accuracy while ensuring the stability of the instrument during long-term operation. 6. The data of sulfur, hydrogen, and water can be supplemented and automatically converted into high and low calorific values after the experiment is completed, which is more in line with the conventional experimental process. The experimental process of adding water, draining, mixing, ignition, temperature measurement, calculation, calibration, and printing is fully automated, avoiding human errors. 8. The machine has self-protection, self diagnostic technology, fast fault finding, and is easy to maintain
