Hydrogen Fluoride Detection Tubes 1.5/b (1.5 - 15 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

Reaction PrincipleHF + Zr (OH)4 / Quinalizarin ─>
[ZrF6]^2 + Quinalizarin
Cross SensitivityIn 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.
