5E-AS3200B Automatic Coulomb Sulfur Analyzer is used to determine the total sulfur content in coal and liquid fuel. A sample is combusted in a dry air atmosphere; the gases evolved go to a electrolytic cell containing platinum indicating electrodes and platinum electrolysis electrodes. A small current is produced as the sulfur reacts with electrodes; the current is balanced and equivalent to the amount of sulfur present in coal.

AS 1038.6.3.3, ASTM D3177, ASTM D4239, ASTM D5016, ISO 19579, GB/T 214, GB/T 25214, BS 1016

1. Easy Operation
1) Auto self-diagnosis.
2) Protect heating components by over temperature alarms and auto heating off function
3) Large volume reagent tube to minimize the maintenance of changing the reagent

2. Cost Saving
The test can be performed without oxygen, and the desiccant can be used repeatedly.

Additional Features for 5E-AS3200B
