Water Vapor Detection Tubes 1/b (1 - 40 mg/l)
For short-term measurements more than 160 Draeger-Tubes are available to measure the spot concentrations of specific gases. Measurement usually takes between 4 seconds and 15 minutes. The tubes are used either manually with the Draeger-Tube Accuro Pump or automatically with the Draeger X-act 5000.
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
Water Vapor Detection Tubes 1/b (1 - 40 mg/l)
| Standard Measuring Range: |
20 to 40 mg/L / 1 to 18 mg/L |
| Number of Strokes (n): |
1 / 2 |
| Time for Measurement: |
approx. 20 sec. / approx. 40 sec. |
| Standard Deviation: |
± 15 to 20 % |
| Color Change: |
yellow ??> turquoise-blue |
| Temperature: |
0 to 50° C |
| Absolute Humidity: |
up to 100% r.h.
Condensation in the tube causes measurement errors. If high r.h. (in excess of 80%) is to be expected, the temperature of the tube should be at least 5 �C higher than ambient temperature. Given a r.h. below 80%, the temperature of the tube should be at least equal to the ambient temperature. |
| Reaction Principle: |
H2O + Mg(ClO4)2 ??> turquoise-blue reaction product |
| Cross Sensitivity: |
Acid gases are liable to cause plus errors. Basic gases are liable to cause minus errors. |
