[Scope of Application]
KZDL-800 microcomputer fully automaticSulfur measuring instrumentThis instrument is mainly used to determine the total sulfur content in combustible substances such as coal, coke, and petroleum. It can make 24 samples at once and can automatically and continuously send samples, achieving unmanned operation and high degree of automation. In addition, it has the function of external electronic balance and can upload data online, which is widely used in industries such as power, coal, metallurgy, chemical, cement, papermaking, environmental protection, geological exploration, and research institutes.

[Technical Features]
1: Adopting a vertical high-temperature cracking furnace and modular component design, the automatic continuous sample feeding mechanism, electrolytic cell, agitator, air purifier and other system components are assembled in one box. The structure is reasonable and the concept is clever, resulting in a compact and aesthetically pleasing instrument.

2: The instrument can be connected to an external electronic balance, and automatic weighing can be achieved by pressing the button when weighing the sample. The automatic continuous sample delivery mechanism can accommodate 24 samples at once and can add samples at any time during the testing process. It also has the functions of queue insertion and re queuing, and the additional samples can be given priority testing opportunities in advance.

3: The entire testing process after sample installation can be unmanned, which improves testing efficiency. The measurement process is automatically controlled by a program: fully automatic continuous sample delivery, fully automatic control of start and end of the experiment, fully automatic coulometric titration, fully automatic data processing and storage, and data printing. In addition, the instrument also has networking capabilities, which can achieve remote data sharing and remote uploading of data reports.

4: Coulombic titration electrolysis current adopts a constant current scheme, and Coulomb integration is implemented by software to make the titration result more stable. Systematic errors can be directly corrected through software to achieve dynamic multi-point calibration, which improves the testing accuracy of various types of samples. The test results are higher thancountryStandard requirements, good repeatability, high accuracy.

5: The furnace adopts new energy-saving materials with good insulation performance, fast heating speed, and is more environmentally friendly, low-carbon, and energy-saving. PID temperature control has high precision, effectively protecting the service life of the furnace and silicon carbon tube. In addition, the function of blowing air on the sample has been added, which enables the sample to burn completely quickly and improves the testing accuracy.

6: The gas path adopts dual air pumps and dual filtration systems, with good air tightness, low failure rate, and stable gas source.

7: The entire instrument structure is designed with the concept of modular components, which are easy to disassemble and interchangeable, making it very convenient for the installation, debugging, maintenance, and subsequent after-sales service of the instrument. Automatic continuous sample delivery mechanism is also availableAs a component, batch platform exchange can be achieved, which is very convenient and solves users' worries.

8: The system design has a dedicated fault diagnosis and detection program. Real time monitoring of various functional components of the instrument during operation, with fault diagnosis, alarm and prompt functions. In addition, it also has a powerful debugging menu, which facilitates on-site installation and debugging of the instrument, as well as diagnosis and troubleshooting of faults. In addition, remote diagnosis and technical support can also be realized through the Internet.

9: The instrument control system adopts the new ARM series microcontroller from the United States, which has fast calculation speed and strong control capability. The software is designed with an embedded multitasking operating system, resulting in stable program structure and strong anti-interference ability. Communication with microcomputers can be achieved through the use of USB technology that supports hot swapping, making it convenient for users to build one machine with multiple controls

10: The microcomputer testing software supports operating system platforms such as WINXP, WIN7, WIN8, and WIN10, and the system is stable. The human-computer interaction interface is friendly and very convenient for operators to learn and use.
