Water Vapor Detection Tubes 1/b (1 - 40 mg/l)
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:
||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.
||± 15 to 20 %
||yellow ──> turquoise-blue
||0 to 50° C
||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.
