Draeger 8103471 Sulfuryl Fluoride 1/a Detector Tubes (5 tests per box)

Application Range:

• Standard Measuring Range: 1 to 5 ppm
• Number of Strokes n: 6
• Time for Measurement: approx. 3 min
• Standard Deviation: ± 30 %
• Color Change: light blue → light pink

Ambient Operating Conditions:

• Temperature: 0 to 40 °C
• Absolute Humidity: 15 to 90 % r.h.
• At 0 to 10 °C, concentrations of sulfuryl fluoride are displayed with approximately half sensitivity.
• At 30 to 40 °C and air humidity < 30 % r.h. the displays can only be recognised as of > 2 ppm.
• At 30 to 40 °C and air humidity > 75 % r. h., concentrations of sulfuryl fluoride are displayed with approximately half sensitivity.

Reaction Principle:

• a) pyrolysis sulfuryl fluoride → HF
• b) HF + zircon / quinalizarin → pink reaction product (HF destroys the quinalizarin/zircon complex by complexation of the zircon)

Cross Sensitivity:

• Fluorinated hydrocarbons are also displayed with different sensitivities.
• Ammonia and other basic gases could, depending on the concentrations, either shorten or prevent the color change.
• The following chemicals have no influence on the display of 3 ppm sulfuryl fluoride:
  • 2 ppm formaldehyde, 5 ppm methyl bromide and 1 ppm phosphine.
  • When the oxygen concentration decreases, the sensitivity decreases.
    • For example, the 3 ppm display at 18 % oxygen is very weak.

Additional Information:

• Do not use in areas subject to explosion hazards.
• Tubes get hot.
• During and shortly after measurement, do not touch the first tube near the black pyrolysis layer.
