Product description
Drager Short Term Detection Tubes - Sulphur Dioxide 20/a (Pack of 10)
These Drager short-term detection tubes are a cost-effective way of measuring sulphur dioxide (20/a). The tubes have a measurement range of 20 to 2000 ppm and a shelf life of 2 years.
Please note that one pack contains 10 tubes.
Short-term detection tubes require the use of the Drager Accuro Gas Detection Pump. Click here to buy this product.
Key Features
- Hard-to-reach places can be accessed and measured using various compatible accessories
- Excellent for on-the-spot measurements
- 10 seconds to 15 minutes is the time frame for readings and is totally dependent on the tube type
- Suitable applications include pre-entry checks, confined space entry, variations in concentration levels and also contamination of breathing areas are amongst a number of potential of applications
Specification
| Application Range | |
| Standard Measuring Range: | 20 to 200 ppm |
| Number of Strokes n: | 10 |
| Time for Measurement: | approx. 3 min |
| Standard Deviation: | ± 10 to 15 % |
| Color Change: | brown yellow --> white |
| Ambient Operating Conditions | |
| Temperature: | 0 to 40 °C |
| Absolute Humidity: | < 30 mg H2O / L |
| Reaction Principle | |
| SO2 + I2 + 2 H2O --> H2SO4 + 2 HI | |
| Cross Sensitivity | |
| Hydrogen sulfide is indicated, with the same sensitivity. It is impossible to measure sulfur dioxide in the presence of hydrogen sulfide. Nitrogen dioxide will shorten the reading. | |
| Extension of the Measuring Range | |
| Using n = 1+3 desorption strokes, multiply the reading by 10; the range of measurement is 200 - 2,000 ppm. The desorption strokes are to be taken in clean air (i.e. free of sulfur dioxide) immediately following the single pump stroke. | |
