Dräger Tubes For Short Term Measurements: Hydrogen Fluoride 1.5/b
Dräger Safety offer a massive range of short-term gas detection tubes for the measurement of various gases. This particular set of tubes is for (Hydrogen Fluoride 1.5/b).
The tubes come in a pack of 10 tubes and have a shelf life of 2 years.
|Standard Measuring Range:||1.5 to 15 ppm|
|Number of Strokes n:||20|
|Time for Measurement:||approx. 2 min|
|Standard Deviation:||± 15 to 20 %|
|Colour Change:||pale blue to pale pink|
Ambient Operating Conditions:
|Temperature:||15 to 30 °C|
|Absolute Humidity||max. 9 mg H2O / L|
HF + Zr(OH)4/Quinalizarin ~> [ZrF6]2- + Quinalizarin
In the presence of higher humidity (> 9 mg H2O / L), hydrogen fluoride mist is generated, which cannot be quantitatively indicated by the detector tube (i.e. the indication is too low). Other halogenated hydrocarbons in the TLV range do not interfere..
