Drager Detection Tubes - Sulfuryl Fluoride 1/a (Pack of 5)
This Drager short-term detection tube measures Sulfuryl Fluoride (1/a) and has a measurement range of 1 to 5 ppm. They have a shelf life of 2 years and come in a pack of 5tubes.
Short-term detection tubes require the use of the Drager Accuro Gas Detection Pump. Click here to buy this product.
- Reach difficult measurement areas with the tubes, pump and accessories
- Carry out measurements on the spot
- Measurement results may take between 10 seconds and 15 minutes depending on the type of tube used
- Applications for use include variations in concentrations in the workplace, contamination of breathing zones, pre-entry checks and confined space entry
|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.
|a) pyrolysis sulfuryl fluoride --> HF
b) HF + zircon / quinalizarin --> pink reaction product (HF destroys the quinalizarin/zircon complex by complexation of the zircon)
|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
|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.|
