Sulfuric Acid Detection Tubes 1/a (1 - 5 mg/m3)
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
Sulfuric Acid Detection Tubes 1/a (1 - 5 mg/m3)
| Standard Measuring Range: |
1 to 5 mg/m3
Discoloration compared to color comparison tube. |
| Number of strokes n: |
100 |
| Time for Measurement: |
approx. 100 min |
| Standard Deviation: |
± 30 % |
| Color Change: |
brown ??> pink violet |
| Temperature: |
5 to 40 °C |
| Absolute Humidity: |
< 15 mg H2O / L |
| Reaction Principle: |
H2SO4 + Barium chloroanilate ??>
Chloranilic acid + Ba2 So4 |
| 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 transferred 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 |
