Draeger 8103691 Benzene 0.25/a Detector Tubes (10 tests per box)

Application Range:

• Standard Measuring Range: 0.25 to 2 ppm / 2 to 10 ppm
• Number of Strokes n: 5 / 1
• Time for Measurement: Approx. 5 min / 1 min
• Standard Deviation: ± 15 %
• Color Change: Light Grey → Dark Grey to Black

Ambient Operating Conditions:

• Temperature: 0 to 40 °C
• Absolute Humidity: max. < 40 mg H2O / L

Reaction Principle:

• Benzene + Alu+ → dark grey to black reaction product

Cross Sensitivity:

• Up to a concentration of approx. 40 ppm (n=5) and 200 ppm (n=1), toluene, xylene and ethyl benzole are kept in the pre-layer where they cause a brown discolouration. 800 ppm n-Oktane (n=5) and 4000 ppm n-Octane (n=1) do not cause any discoluration in the indicating layer.
