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 is used to determine the trace sulfur 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), SH/T0222, GB/T 11061.4-2010, GB/T 6324.4-1986, GB/T 12688.6-1990, GB/T 11141-1989, SY/T7508-1997, ASTM D3120, ASTM D3246.

I. Main technical features
1. Micro-coulometry technology. PC equipped. Windows OS.Easy to operate.
2. Oxidation style. It determines the sulfur or chlorine in petrochemicals as per Faraday's Law.
