Summary
   This instrument uses micro-coulometry technology computer to control the micro-coulomb titration. It’s the newest product, having reliable result, easy to operate, stable performance, easy to install to and so on. It can be used to determine the trace sulfur, chlorine of petro-chemical products. It is widely used in petroleum, chemical industry, and scientific research institutions.Standards: SH/T0253 Petroleum products-Determination of total sulfur content (Coulometry), ASTM D3120, ASTM D3246, SH/T0254, SH/T0222, GB/T 11061.4-2010, GB/T 6324.4-1986, GB/T 12688.6-1990, GB/T 11141-1989, ASTM D5808-03， ASTM D5808-09a，ASTM D5194-06，SY/T7508-1997，SH／T1757-2006，GB/T 18612-2001.
