Description
Dräger-Tube Sulfuric Acid 1/a
PN: 6728781
Dräger-Tubes™ are used together with a Dräger tube pump for measurements of gases, vapors and aerosols, usually in air, and are one of the classic methods of gas analysis. This Dräger-Tube is used for the detection of sulfuric acid and has the following standard measuring range: 1-5 mg/m³ Measurements: 9
| Application Range | |
| Standard Measuring Range | 1 to 5 mg /m3 |
| Number of Strokes n | 100 |
| Time for Measurement | approx. 100 min |
| Standard Deviation | ± 30% |
| Color Change | brown to pink violet |
| Ambient Operating Conditions | |
| Temperature | 5 to 40 °C |
| Absolute Humidity | <15 mg H2O/L |
| Cross Sensitivity |
| Sulfur trioxide in the gaseous form is not indicated, but in the presence of atmospheric humidity this forms sulfuric acid aerosols, which are indicated. Soluble sulfates and other aerosol forming acids are also indicated but with different sensitivities . It is impossible to measure sulfuric acid in the presence of these substances. |
| Additional Information |
| After performing the required 100 pump strokes the reagent ampoule must be broken and the liquid completely onto the brown reagent layer. Wait one minute before drawing the liquid carefully through the brown layer with approx. 1/4 pump stroke into the indication chamber. The measurement must be evaluated immediately |
