II Scope of application:

Suitable for the determination of total sulfur in materials such as lignite, bituminous coal, anthracite, coke, dry coal samples of coal water slurry, and heavy oil in industries such as electricity, coal mining, metallurgy, chemical engineering, cement, geological exploration, and scientific research institutions.

IIITechnical parameters:

1. The measurement range of sulfur is 0-100%.
2. Resolution: 0.01%
3. Sample combustion analysis time: 3-5 minutes, including 45 seconds at 700 ℃ and 2-4 minutes at 1050 ℃, to automatically determine the titration endpoint.
4. Temperature control: Ensure an accuracy of 1.0 level in the high temperature range of 0-1100 ℃, with an external WRP (S-value) platinum rhodium 10 platinum thermocouple; The heating element is a silicon carbon tube, with a high temperature zone length of ≥ 90 millimeters and a temperature of 1150 ℃± 5 ℃ (temperature can be adjusted as needed), with a value of 10 Ω for silicon carbon tubes.
5. Heating rate: 25-30 ℃/min, can rise to 1050 ℃ in ≤ 30 minutes.
6. Electrolytic cell: with a capacity of 400 milliliters.
7. Stability of the instrument: The instrument enters a stable state after 5 minutes of startup.
8. Power supply: 220V ± 20% 50Hz

4 Performance characteristics:
1. Automatically determining the endpoint of titration has shortened the experimental time.
2. Adopting PID control of furnace flow and automatic adjustment of furnace flow size can extend the service life of silicon carbon tubes by twice compared to traditional controllers.
(Automatic control of current from small to large)
3. The sample delivery mechanism adopts electronic switches, which have high reliability.
4. There will be no over electrolysis phenomenon due to the sequence of on/off.
5. Automatically turn on electrolysis.
6. With high automation and small size, it is currently the ideal sulfur measuring instrument in the laboratory.
7. An online electronic balance is available.
