Chlorine Detection Tubes 0.3/b (0.3 - 10 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, 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: |
0.3 to 5 ppm |
| Number of Strokes (n): |
20 |
| Time for Measurement: |
approx. 8 min. |
| Standard Deviation: |
±10 to 15 % |
| Color Change: |
pale green-gray ─> brown |
| Temperature: |
0 to 40° C |
| Absolute Humidity: |
< 15 mg H2O / L |
| Reaction Principle: |
Cl2 + o-tolidine ──> brown reaction product |
| Cross Sensitivity: |
Bromine is indicated with the same sensitivity, but with a paler discoloration. Chlorine dioxide is indicated with different sensitivity. Nitrogen dioxide is indicated as well, but with a paler discoloration and lower sensitivity. |
| Extension of the Measuring Range: |
Using n=10 stroke, multiply the reading by 2, the measuring range will be 0.6 to 10 ppm. |
