IR Carbon Sulfur Analyzer is developed for the accurate and safe analysis of carbon and sulfur in inorganic samples. It can rapidly and accurately conduct content determination of carbon and sulfur in materials like steel, iron, alloy, nonferrous metals, etc. This is a high-tech product that integrates optical, electrical, computer, and analytical technology into one. - It can fleetly and exactly measure the carbon and sulfur in steel, iron, alloy, nonferrous metals, and other materials. - Radio circuit: The design of high-duty radio circuit and the application of 2.5KVA HF pliotron, frequency : 20MHz. Military-purpose ceramic vacuum tubes and ceramic vacuum capacitors. - HF control circuit: It is used for automatic detection of the electromagnetic valve, the elevation or descent of cylinder and the performance of HF unit. Automatic overtime/overflow alarming system enables the HF furnace to work under normal condition. - The optional current/voltage/power regulator for furnace temperature control: It is applicable to samples of various materials.
