Draeger Tube Sulfur Dioxide 1/a CH31701

Description

The Draeger Tube Sulfur Dioxide 1/a CH31701 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: 1 to 25 ppm
• Number of Strokes n: 10
• Time for Measurement: approx. 3 min
• Standard Deviation: ± 10 to 15 %
• Color Change: grey blue → white

 

Ambient Operating Conditions

• Temperature: 15 to 25 °C
• Absolute Humidity: 3 to 20 mg H₂O / L

 

Reaction Principle

• SO2 + I2 + 2 H2O → H2SO4 + 2 HI

 

Cross Sensitivity

Hydrogen sulfide in the TLV range is retained in the pre-layer and does not interfere. Nitrogen dioxide will shorten the reading.

Application Range

Use in SimultanTest CO2

• Standard Measuring Range: 0.5 to 2 ppm
• Test Volume: 2 L
• Flow Rate: approx. 0.2 L / min
• Time for Measurement: in the Aerotest CO2: 10 min in the Multi Test (for CO2): 12 min
• Standard Deviation: ± 30 %
• Color Change: greyblue → white

 

Ambient Operating Conditions

• Temperature: 15 to 25 °C
• Absolute Humidity: 3 to 20 mg H₂O / L
• Pressure: The tube may only be used for depressurized compressed air

 

Reaction Principle

Starch

• SO2 + I2 + 2 H2O → H2SO4 + 2 HI

 

Cross Sensitivity

Hydrogen sulfide in the TLV range is retained in the pre-layer and thus does not affect the indication. Nitrogen dioxide will shorten the reading. Draeger Tube Sulfur Dioxide 1/a CH31701

 

Evaluation

• reading on the (n=10) scale x 0.2 = ppm SO2 (applies only for scale range 2.5 to 10 ppm)

Accurate and reliable results

Draeger-Tubes with the Accuro Pump deliver the most accurate results. 60+ years of manufacturing colorimetric tubes. The bellows pump design delivers consistent volume. Individual calibration of each batch of Draeger gas detection tubes Sulfur Dioxide included, accomplishes quality assurance. Every batch undergoes testing at regular intervals, throughout the two year shelf life, to guarantee accuracy over the entire life of the tubes.

Draeger Sulfur Dioxide Detector Tubes

Collect the hazardous substances in the air by using a suitable medium such as activated carbon, silica gel, or molecular sieves. Then analyze the sample in a laboratory with the aid of instrumental analysis.

Suitable for complex cases

Draeger sampling tubes and systems allow identification and measurement of different substances even under difficult conditions. Use Draeger Tubes to simultaneously and accurately measure very complex mixtures of substances or cases in which several similar substances are present. Dräger Tube Sulfur Dioxide 1/a has the Draeger SKU CH31701.

Dräger accuro
