ST-1551 thiol sulfur analyzer complies with GB/T1792 standard，Use potentiometric titration method. Suitable for determining thiol sulfur in hydrogen sulfide free jet fuel, gasoline, kerosene, and light diesel. The determination of thiol sulfur is of great significance in evaluating the odor of jet fuel, gasoline, kerosene, and light diesel, its adverse effects on rubber components of fuel systems, and its corrosion on fuel systems.The thiol sulfur analyzer consists of a host, an imported titration device, and a computer. With the support of application software, the host can achieve automatic titration, automatic fluid replenishment, and automatic determination of thiol sulfur content in petroleum products.It can be widely used in departments such as power, petroleum, chemical, commercial inspection, universities, and scientific research.
