Description
Dräger-Tube Carbon Monoxide 8/a (10)
PN: CH19701
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 carbon monoxide and has the following standard measuring range: 8-150 ppm Measurements: 10
| Application Range | |
| Standard Measuring Range | 8 to 150 ppm |
| Number of Strokes n | 10 |
| Time for Measurement | approx. 2 min |
| Standard Deviation | ± 10 to 15% |
| Color Change | white to pale brown |
| Ambient Operating Conditions | |
| Temperature | 0 to 50 °C |
| Absolute Humidity | < 50 mg H2O/L |
| Cross Sensitivity |
| Acetylene is also indicated , however with less sensitivity . Petroleum hydrocarbons, benzene, halogenated hydrocarbons and hydrogen sulfide are retained in the pre-layer. In the case higher concentration of interfering hydrocarbons, use should be made of a carbon pre-tube (CH 24 101). Higher concentration of easily cleavable halogenated hydrocarbons(e.g. trichloroethylene), are liable to form chromyl chloride in the pre-layer which changes the indicating layer to yellow-brown . CO determination is impossible in the case of high olefin concentration . |
