Fixed instrument performance characteristics, use requirements

The performance characteristics of the sulfur analyzer use an integrated structural design, eliminating general-purpose computers and printers, greatly reducing the volume and footprint, and also reducing the failure rate.

Using the latest 16-bit microcontroller control. With a large-screen graphic LCD display, all information and menus are displayed in Chinese characters, which is easy to see at a glance.

The overall structural design is reasonable, the appearance is beautiful, exquisite, the performance is stable, the result is accurate and reliable.

With the self-diagnosis function of the power-on, some key hardware is self-checked, and the possible faults are reported immediately, so that the instrument is in the best working condition.

With a communication interface, the data and test results of the test process can be sent to the computer for display, saving and printing in real time.

The air pump and the stirring are automatically turned on to avoid human error, and it is extremely convenient to replace the desiccant.

The requirements of the use of sulfur analyzer 1. Turn on the power: press the power switch, the instrument will conduct self-test after power on, and automatically increase the temperature after the self-test passes.

2. When the furnace temperature rises to 1100°C, start the carrier gas system and check the air tightness. The method is as follows: The hemostatic clip is used to clamp the air inlet and the discharge tube of the electrolytic cell. At this time, the float of the gas flow meter should be seen to slowly decrease. If it falls below 500 ml/min, it means that it is qualified; otherwise, the problem should be checked and solved before continuing. Do experiments.

3, then open the liquid discharge tube and hemostatic clip, the electrolyte into the electrolysis cell, the electrolyte into the electrolysis cell, the electrolyte generally does not exceed 2 cm above the electrode plate. Adjust the stirring speed (in the case of the mixer without losing the step, the stirring speed is faster and better), and it is not allowed to change the stirring speed during the experiment, otherwise the experiment is invalid. Finally adjust the flow meter so that the airflow is about 1000ml/min. During the experiment, you should always observe the air flow. If it is too low, you should adjust it.

4, when the furnace temperature rose to 1150 °C, you can start experimenting. 1-3 waste samples must be made before testing official samples. If the electrolyte is not used for a long time and the color is very dark, it is better to use coal with high sulfur content as waste sample until the result is not zero and the electrolyte color becomes light. The purpose of the waste sample is to make the electrolyte meet the requirements of the instrument. Balanced state. A batch of samples is best done continuously, such as the middle break for a relatively long time (more than half an hour), in order to ensure accuracy, it is best to add a waste sample before continuing the experiment.

5. After the experiment is completed, turn off the carrier gas system, and finally discharge the electrolyte, and clean the electrolytic cell with distilled water.

6. Return to the main menu. The instrument with automatic shutdown function uses automatic shutdown. The other models of sulfur analyzer turn off the power switch and turn off the main power before off duty.

The total sulfur content of coal is one of the important indicators for evaluating coal quality, and it is also one of the main components of atmospheric pollution. Therefore, the coal production sector and the coal sectors such as chemical fertilizers, power generation, civil use, coking, and building materials all attach great importance to the analysis of total sulfur in coal. The instrument uses iodine as coulometric titrant. The total sulfur content of Chinese character liquid crystal display samples, due to the use of new technology, the accuracy and stability of the measurement is much higher than the national standard, each measurement time is about 5 minutes.
