Draeger Tube Hydrogen Sulfide + Sulfur Dioxide 0.2%/a CH28201

Description

The Draeger Tube Hydrogen Sulfide + Sulfur Dioxide 0.2%/a CH28201 is high precision. The Dräger sampling tubes and systems provide very reliable results, even with complex compounds and mixtures of substances.

Application Range

• Standard Measuring Range: 0.2 to 7 vol. %
• Number of Strokes n: 1 + 2 desorption strokes in clean air
• Time for Measurement: approx. 2 min
• Standard Deviation: ± 5 to 10 %
• Color Change: brown → bright yellow

 

Ambient Operating Conditions

• Temperature: 0 to 40 °C
• Absolute Humidity: max. 40 mg H₂O / L

 

Reaction Principle

• H2S + I2 → 2 HI + S2
• SO2 + I2 + 2H2O → 2 HI + H2SO4

Cross Sensitivity

All substances oxidized by iodine are indicated, but with different sensitivities. It is impossible to measure hydrogen sulfide and sulfur dioxide in the presence of such substances.

Extension of the Measuring Range

Using n = 10, divide the reading by 10; the measuring range will be 0.02 to 0.7 vol. %.
