Sulfuric Fluoride Detection Tubes 1/a (1 -5 ppm)

For short-term measurements more than 160 Draeger-Tubes are available to measure the so-called spot concentrations of specific gases. A wide range of different gases and vapours can be detected and measured, e.g.: Determining and measuring concentration peaks, Measuring personal exposure in the inhalation area, Detecting leaks in pipelines, gas installations etc., and Air analysis in sewers, shafts and confined spaces.

Contains 10 tubes

Please Note: This is a Haz-Mat product and must be shipped Haz-mat Freight. Extra shipping fees will apply.

Standard Measuring Range1 to 5 ppm
Number of strokes n:6
Time for Measurementapprox. 3 min.
Standard Deviation± 30 %
Color Changelight blue ──> light pink
Temperature0 to 40 °C
Absolute Humidity15 to 90 % r.h.

At 0 to 10°C, concentrations of sulfuryl
fluoride are displayed with approx. half
sensitivity. 

At 30 to 40°C and air humidity <30% r.h.
the displays can only be recognized as
of >2 ppm.

At 30 to 40°C and air humidity >75 % r.h.,
concentrations of sulfuryl fluoride are
displayed with approx. half sensitivity.
Reaction Principlea) pyrolysis sulfuryl fluoride ──> HF
b) HF + zircon / quinalizarin ──> pink
   reaction product
   (HF destroys the quinalizarin/zircon 
   complex by complexation of the zircon)
Cross SensitivityFluorinated 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, 3
ppm display at 18% oxygen is very weak.
