Microcomputer fully automatic sulfur analyzer, intelligent Han display sulfur analyzer, coal quality analysis, coal coke, petroleum sulfur content detector

1、 Product Introduction:

This instrument is made based on the principle of Coulombic titration (see GB/T 214-2007). The temperature control of the high-temperature furnace and the measurement of Coulombic titration results are carried out by a microcontroller system. The data processing and display are performed by the microcontroller system, and human-machine interaction information is exchanged, and corresponding control commands are sent to the microcontroller system. When the device is working offline, the microcontroller system independently completes the corresponding work. When the device is operating in the microcomputer state, the microcontroller system cooperates with the microcomputer to complete the corresponding work.

2、 Characteristics

1. This system is used to measure the sulfur content of combustible substances such as coal, coke, and petroleum.

2. The entire testing process is automatically controlled by a microcomputer and can also be performed independently of the microcomputer.

3. Calibration is convenient and intuitive during the experimental process.

4. The measurement results can be stored for a long time, and can be queried and printed.

5. The system operating temperature can be set by users through software between 800 ℃ and -1150 ℃ (1050 ℃ for coal measurement and 800 ℃ for oil measurement).

6. The standard RS232 serial interface is used between the microcomputer and microcontroller system, which has the characteristics of simple wiring, reliable transmission, long transmission distance, and low failure rate.

7. The microcontroller system is responsible for controlling the temperature of the high-temperature furnace, collecting measurement data, and transmitting the data to the main control microcomputer through a serial line for data processing. The overall performance of the system is greatly improved by the cooperation with the main program of the microcomputer.

8. This system places the high-temperature furnace, magnetic stirrer, air purification device, electrolytic cell, automatic sample delivery mechanism, and microcontroller control circuit in the same chassis, making the entire system beautiful, small in size, easy to place and connect, and simple to operate and maintain.
