Sulfur measuring instrument

intelligentSulfur measuring instrumentIt is a new generation fully automatic instrument independently developed by our company.According to the principle of Coulombic titration (see GB/T 214-2007）Made. The temperature control of the high-temperature furnace and the measurement of Coulombic titration results are carried out by a microcontroller system7 inchesThe LCD screen displays and sends corresponding control commands to the microcontroller system, which independently completes the corresponding work.

1Sulfur measuring instrumentOverview of System Functions

The system is mainly used to measure the sulfur content of combustible substances such as coal, activated carbon, coke, and petroleum.

The entire testing process is automatically completed by microcomputer control.

3. Errors can be automatically corrected through experiments.

4. The test results are permanently stored and can be viewed and printed.

5. Automatic temperature compensation, with a temperature measurement error of 5%.

6. It has functions such as automatic startup protection and overcurrent protection for silicon carbon tubes.

7.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.
