Draeger 6733181 Ozone 0.05/b Detector Tubes (10 tests per box)

Application Range:

• Standard Measuring Range: 0.05 to 0.7 ppm
• Number of Strokes n: 10
• Time for Measurement: approx. 3 min
• Standard Deviation: ± 10 to 15 %
• Color Change: Pale Blue → White

Ambient Operating Conditions:

• Temperature: 0 to 40 °C
• Absolute Humidity: 2 to 30 mg H2O / L

Reaction Principle:

• O3 + indigo → isatinel

Cross Sensitivity:

• No interference by:
  • 1 ppm sulfur dioxide
  • 1 ppm chlorine
  • 1 ppm nitrogen dioxide
  • Higher concentrations of chlorine and nitrogen dioxide discolor the indicating layer a diffuse white to pale grey.

Extension of the Measuring Range:

• Using n = 5, multiply the reading by 2; the measuring range will be 0.1 to 1.4 ppm.
• Using n = 100, divide the reading by 10; the range of measurement is 0.005 to 0.07 ppm.
