Product description
Drager Short Term Detection Tubes - Hydrogen 0.5%/a (Pack of 10)
Drager short-term detection tubes – suitable for Hydrogen (0.5%/a) with a measurement range of 0.5 to 3 vol. %.
They have a shelf life of 2 years and come in a pack of 10 tubes.
The Accuro Gas Detection Pump from Draeger Safety is required to use short-term gas detection tubes. View more information on this product by clicking here .
Key Features
- Designed for short-term, on-the-spot measurement
- Can take between 10 seconds to 15 minutes to gather a reading
- Applications may include concentration fluctuations in the workplace, measurement of contaminants in breathing zone, and confined spaces
- Can be used as pre-entry checks
Specification
| Application Range | |
| Standard Measuring Range: | 0.5 to 3 vol. % |
| Number of Strokes n: | 5 |
| Time for Measurement: | approx. 1 min |
| Standard Deviation: | ± 10 to 15 % |
| Color Change: | yellow/green - pink |
| Ambient Operating Conditions | |
| Temperature: | 5 to 40 °C |
| Absolute Humidity: | < 30 mg H2O / L |
| Reaction Principle | |
| a) H2 + 1⁄2 O2 - H2O b) H2O + SeO2 + H2SO4 - pink reaction product |
|
| Cross Sensitivity | |
| Up to 1,000 ppm CO has no influence on the indication; higher concentrations lead to lower measurement results. Acetylene and alcohols react similarly to hydrogen. | |
| Additional Information | |
| Do not use in potentially explosive areas. Qualify before use with a combustible gas monitor. When the hydrogen concentration is above 3 vol. % the catalysis layer heats up during the measurement with a reddish glow. Determination of hydrogen in air with at least 5 vol. % O2. | |
