The total sulfur content of coal is an important indicator of coal quality detection; rapid sulfur meter for determination of total sulfur in coal would produce some deviations. Through the analysis of the cause of the deviation of sulfur detector and from electrolyte use points, weighing instrument calibration, air tightness, gas flow velocity, the determination of standard curve, coal sample preparation weighing requirements, and avoiding human error, etc., the improvement suggestions for deviation in coal total sulfur content detection were put forward in order to improve the total sulfur detection accuracy.
