Epichlorohydrin Detection Tubes 5/b (5 - 80 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 vapors can be detected and measured, such as:
- Determining and measuring concentration peaks
- Measuring personal exposure in the inhalation area
- Detecting leaks in pipelines, gas installations etc.
- Air analysis in sewers, shafts and confined spaces
|Standard Measuring Range:
||5 to 80 ppm
|Number of Strokes (n):
|Time for Measurement:
||approx. 8 min
||±15 to 20%
||pale gray ─> yellow orange
||10 to 40° C
||5 to 15 mg H2O / L
||Epichlorohydrin + CrVI ──> Cl2
Cl2 + o-tolidine ──> yellow orange reaction product
||Other chlorinated hydrocarbons are indicated as well but with different sensitivities. It is not possible to measure epichlorohydrine in the presence of free halogens and hydrogen halides in the TLV range because they are indicated as well. Petroleum hydrocarbons cause low readings.
