Polytest Detection Tubes - Qualitative
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

| Standard Measuring Range: |
Qualitative determination of easily oxidable substances. |
| Number of strokes n: |

| Time for Measurement: |
approx. 1.5 min. |
| Color Change: |
white ??> brown, green or violet (depending on substance) |
| Temperature: |
0 to 50 �C |
| Absolute Humidity: |
max 50 mg H2O / L |

| Cross Sensitivity: |
Based on the reaction principle, many easily oxidised compounds are indicated, several examples are shown below:
- 2000 ppm acetone 10 ppm acetylene
- 50 ppm ethylene 1 ppm arsine
- 10 ppm octane 50 ppm benzene
- 500 ppm propane 100 ppm butane
- 5 ppm carbon monoxide 10 ppm styrene
- 1 ppm carbon disulfide 20 ppm perchloroethylene
- 2 ppm hydrogen sulfide 10 ppm toluene, Xylene
Methane, ethane, hydrogen and carbon dioxide are not indicated

| Additional Information |
If there is no reading, this does not always indicate that easily oxidizable substances are not present. In the individual case, the use of Dr�ger Polytest should be qualified by independent methods, particularly when combustible gases and vapors close to the LEL, or toxic substances are suspected. |
