Scope of application:

Suitable for the determination of total sulfur in coal, coke, petroleum and other substances in power, coal mining, metallurgy, chemical, cement geological exploration, scientific research institutions and other departments.

Performance Introduction:

The KZDL-4 fast intelligent sulfur analyzer is equipped with a male display screen for intuitive operation, keyboard operation, and computer program control. Chinese prompts with illustrations and menu style operation interface, intuitiveEasy to learn and operate, the instrument has a simple structure and stable and reliable performance.

Equipped with real-time on-site monitoring, diagnosis, and prompt functions for potential faults, it can eliminate potential faults in their early stages and reduce the possibility of faults continuing to develop In addition, detailed and illustrated troubleshooting steps can greatly reduce the after-sales maintenance costs and energy of the instrument

The fuzzy PID speed temperature control program used intelligently judges and adapts to silicon carbon tubes with different resistance values, linearizes temperature rise, and has high temperature control accuracy Additionally, it provides excellent protectionDeveloped silicon carbon nanotubes and greatly extended their service life.

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

The composition consists of a high-temperature furnace, a magnetic stirrer, an air purification device, an electrolytic cell, an automatic sample feeding mechanism, and a microcontroller control circuit.

Technical parameters:
