Methyl Acrylate Detection Tubes 5/a (5 - 200 ppm)
For short-term measurements more than 160 Draeger Tubes are available to measure the so called spot concentrations of specific gases.
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
|Standard Measuring Range:
||5 to 200 ppm
|Number of strokes n:
|Time for Measurement:
||approx. 5 min
||± 30 to 40 %
||yellow ──> blue
||15 to 35°C
||5 to 12 mg H2O / L
||CH2=CH-COOCH3 + Pd-Molybdate complex ──> blue reaction product
||Other compounds with C=C double bonds are indicated, but with different sensitivities. It is impossible to differentiate between them. It is impossible to measure methyl acrylate in the presence of hydrogen sulfide. Hydrogen sulfide will discolor the indicating layer black. Carbon monoxide in high concentrations discolors the indicating layer pale blue grey.
