Main features of SDS Series Coulometry Sulphur Analyzers：

The test results are accurate without secondary correction, which stands for the highest level of technology of Coulometry Sulphur Analyzers

The influences that secondary correction affects results:
Coulometry or Infrared Sulphur Analyzers need to be corrected for system deviation (First correction) and nonlinear index, during which 5 to 7 standard samples of different standard values are needed tested several times to form a calibration curve. It has proved that with the increase times of correction, it might lead to fantastic deviation results of the test data.

Dispensed with secondary correction, they can provide customers with the following experience:
Omitted the operating procedure of secondary correction, the debugging and operation of the instrument are easy.
The results are linear and accurate.
They can ensure accurate test results even the sulphur content of the coal sample is unknown.
