Equipment Name: Automatic Coal Total Sulfur Determinator
Functions and Performance Requirements of the Automatic Coal Total Sulfur Determinator:
The Automatic Coal Total Sulfur Determinator is primarily used to measure the sulfur content in coke and coal. Based on coulometric analysis, it conducts electrolytic reactions in the electrolyte, and the sulfur content in the test sample is determined by the amount of electricity consumed in the electrochemical reactions at the electrodes. The equipment has the following functions:
2.1 Automatically completes the measurement of total sulfur content in coal. One to 24 samples can be placed at a time, and the entire process—including weighing, sample feeding, testing, saving, and printing results—is performed automatically and continuously without manual intervention, eliminating errors caused by human factors.
2.2 Built-in electronic balance automatically weighs samples, automatically and continuously feeds samples, automatically calculates test results, automatically corrects test results, and automatically prints reports.
2.3 Multiple dynamic calibration methods (primary, secondary, and tertiary) are available to ensure measurement accuracy for low, medium, and high sulfur content.
2.4 Equipped with a voltage reduction device and PID temperature control technology to extend the service life of heating elements, with accurate temperature control and fast heating speed.
2.5 Self-test can be performed upon startup, displaying self-test information.
2.6 Uses a DC air pump with stable flow and low noise.
2.7 During the experiment, samples can be inserted or added if automatic weighing is not performed.
2.8 Sample codes and weight information are automatically transmitted; test results are backed up and uploaded. The device can be networked for automatic data sharing.
