Introduction: HDL-W microcomputer automatic sulfur analyzer (also known as: WCL-A microcomputer automatic sulfur analyzer) is based on GB / T214 coulometric titration method for determination. On the basis of analyzing and summarizing the current domestic production of single-chip sulfur tester, based on learning from each other, optimize combination, the use of computer technology to develop a new type of intelligent analysis instrument design, all the testing process by the PC series microcomputer control is common sulfur Instrument replacement products. The products are mainly used for the determination of total sulfur content in various minerals such as coal, steel, electricity, metallurgy, geology and other systems, and can be used by laboratories of coal, electricity, metallurgy and geological exploration departments. Features: 1, data computing, processing, analysis and strong. The compensation formula can be used to accurately correct the test data and eliminate the step correction error in the single chip microcomputer control mode. Automated analysis of several test results for each substance and calculation of the water content data for the material resulted in a final milligrams of dry sulfur content. 2, Test reports can be automatically generated test records on the test time, sample weight, moisture, sample delivery units, laboratory data and other content, and can be stored in the computer for a long time, for any call or print the report. 3, strong transportability, data resources can be shared. The instrument uses 586 or above models for analysis of the host. The instrument can enter a variety of computing networks, data transmission through the network or call the data. 4, easy to operate, easy to learn and understand, from the open computer to the beginning of the test, each step has a Chinese prompts, operators have a junior high school education will be able to master the use of this machine. 5, state analysis and intelligent judge function. The machine can automatically analyze and determine the test data during the testing process and automatically control the burning time of the porcelain boat in the furnace according to the sulfur content of the coal sample. The longest burning time of 5 minutes, all the testing process by the microcomputer automatically controlled operation. 6, the instrument in the room temperature environment of 10 ℃ -35 ℃, do not need to be zero can guarantee the accuracy of the data. Unique to prevent the "wrong electrolysis" function, extend the use of electrolyte; Stirring soft start steady speed characteristics, so that more uniform mixing, and without stalling. Therefore, as long as the stirring speed adjusted to the appropriate size, each time you turn on the mixer will automatically climb to the set speed, steady work. 7, enter the water value, the system test results can be compensated. 8, the whole structure with integrated design, compact coordination, nice. The furnace adopts the new insulation structure, which is small in size and good in insulation. The airflow in the furnace enters the pool from the top of the electrolytic cell, effectively preventing the backflow of the electrolyte. Specifications: 1, sulfur measurement range: 0-99.99%. 2, the sample combustion analysis time: about 5 minutes, of which stay at 700 ℃ 45 seconds, 1150 ℃ stay at 4 minutes and 45 seconds. 3, the temperature control accuracy of less than three thousandths, the temperature sensor for the platinum and rhodium platinum thermocouple, heating silicon carbide tube, length: 340mm. 4, heating rate: not exceeding the silicon carbon tube rated voltage, current conditions, up to 1200 ℃ within 30 minutes. 5, electrolytic cell volume of 400 ml, electrolytic platinum electrode area 10 × 15mm. 6, power supply: 220V ± 10% 50HZ. 7, power: 3kw 8, the whole machine volume: 540mm (length) × 460mm (width) × 450mm (height) 9, the whole weight: ≤ 38 kg
