Draeger 6733051 Carbon Monoxide 2/a Detector Tubes (10 tests per box)

Application Range:

• Standard Measuring Range: 2 to 60 ppm / 25 to 300 ppm
• Number of Strokes n: 10 / 2
• Time for Measurement: Approx. 4 min / 50 sec
• Standard Deviation: ± 10 to 15 %
• Color Change: White → Brownish

Ambient Operating Conditions:

• Temperature: 0 to 50 °C
• Absolute Humidity: 2 to 20 mg H2O / L

Reaction Principle:

• 5 CO + I2O5 → I2 + 5 CO2

Cross Sensitivity:

• The following have no influence on the display of 10 ppm CO (respectively):
  • 100 ppm hydrogen sulphide
  • 50 ppm sulphur dioxide
  • 15 ppm nitrogen dioxide
  • 10 ppm CO + 200 ppm octane: display approx. 30 ppm
  • 10 ppm CO + 40 ppm butadiene: display approx. 15 ppm
  • 10 ppm CO + 30 (100) ppm benzene: display approx. 15 (20 - 30) ppm
  • 10 ppm CO + 40 ppm chloroform: display approx. 60 ppm
  • 10 (60) ppm acetylene: display approx. 5 (15) ppm
  • With the insertion of a carbon attachment tube (CH 24101), 10 ppm CO can still be measured in the presence of 10000 ppm n-octane
