Formic Acid Detection Tubes 1/a (1 - 15 ppm)
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
Formic Acid Detection Tubes 1/a (1 - 15 ppm)
| Standard Measuring Range: |
1 to 15 ppm |
| Number of Strokes (n): |
20 |
| Time for Measurement: |
approx. 3 min |
| Standard Deviation: |
10 to 15 % |
| Color Change: |
blue violet ?> yellow |
| Temperature: |
10 to 50 C |
| Absolute Humidity: |
< 30 mg H2O / L |
| Reaction Principle: |
HCOOH + pH indicator ??> yellow reaction product |
| Cross Sensitivity: |
It is impossible to measure formic acid in the presence of other acids. Organic acids are indicated by the same color change, but partly with different sensitivity. Mineral acids, e.g. hydrochloric acid are indicated with different sensitivity and by red color. |
