Description
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.
Application Range:
| 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 |
Reaction Principle:
HF + Zr(OH)4/Quinalizarin ~> [ZrF6]2- + Quinalizarin
Cross Sensitivity:
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..
