1.1 Introduction (ZHDW-2000 microcomputer automatic calorimeter)
This system runs on Windows95 or Windows98 and above systems, human-computer interaction, ready to use, the perfect combination of menu methods and shortcut keys, mouse and keyboard operation, flexible and convenient. The software adopts object-oriented programming method, adopts modular management technology, multi-task execution, easy to upgrade the system; adopts advanced serial communication technology, integrates system control and data management, has good compatibility, is easy to maintain, and overcomes the computer interface board The disadvantage of the tank is that it has a wide range of adaptability. The use of this technology in calorimeter products is at the leading level in the country; it uses scientific and effective algorithms, high data accuracy, and stable and reliable system.
The ZDHW-2000 microcomputer automatic calorimeter is mainly composed of a constant temperature calorimeter and a microcomputer calorimeter control system. It is a multi-function, highly automated calorie that is automatically controlled by a computer system and can perform other data and word processing. Measuring instrument; this instrument is mainly used for the determination of the calorific value of combustible substances such as coal, petroleum, chemical, food, wood, explosives, etc.
1.2 Main performance indicators

9. Power supply 220V ± 10%
1.3 Instrument characteristics
1. Adopt microcomputer control, keep all the functions of the computer, and can use all kinds of general software, use calorimeter measuring system to automatically calibrate the energy equivalent (heat capacity) of the heating system and measure the calorific value Input sulfur, moisture, hydrogen and other data to convert and print the results of cartridge calorific value, high calorific value, and low calorific value.
2. The inner cylinder of the constant temperature calorimeter adopts electric stirring of sheet blades, and the stirring of the outer cylinder adopts submersible electric stirring, which makes the stirring more uniform and more convenient. The instrument uses fused cotton ignition method.
3. ZDHW-2000 microcomputer automatic calorimeter is used as a single-tube calorimeter system. If two calorimeters are controlled asynchronously, please select ZDHW-2000A microcomputer automatic calorimeter system.
4. The operation of the calorimeter is carried out under the WINDOWS operating system. The whole process of the operation is prompted by Chinese characters, human-computer interaction, and it is ready to use. Follow the prompts to complete the test.
