The carbon-sulfur combined analyzer is a new generation of steel analysis instrument developed on the basis of mature technology based on the national standard gas volume method and iodometric method using advanced sensing technology. Used for the quantitative analysis of carbon and sulfur in steel, iron and other materials. The carbon content method was used for carbon measurement, and the iodometric method was used for sulfur measurement.

The carbon-sulfur combined measuring analyzer adopts a precise sensor to realize the digital display of the measurement results, read the content directly, and can automatically print the test results, overcoming the visual errors and conversion errors that cannot be overcome in the previous gas readings, and improving the measurement accuracy. The control circuit adopts advanced single-chip technology and works with Darlington-driven solenoid valves. Oxygen, which is essential for various combustion furnaces, is used as a power source to basically achieve non-contact operation of the control process.

The carbon-sulfur combined analyzer test process was automated, and the fluids in the grid were absorbed. The calibration was performed using the standard line quality (abbreviated as standard sample) and the digital display was read directly. The influence of barometric temperature is overcome by the standard sample reference, no conversion is needed, and the measurement speed and precision are greatly improved. Carbon-sulfur combined analyzers can be used with arc burners and can also be used with other types of burners, such as tube furnaces and high frequency induction furnaces. QR-4 carbon-sulfur analyzer adopts the principle of Chinese national standard measurement (carbon gas volume method, sulfur using iodometric method). It is equipped with an electronic balance to achieve indefinite sample measurement, and touch-type membrane button full Chinese menu operation. , And can store four working curves, test results of large-screen liquid crystal display and print directly, carbon can be displayed to three decimal places, sulfur can be displayed to four decimal places, its accuracy is better than the Chinese national standard.
