Carbon Monoxide 2/a, 2 - 60 PPM, Part # 6733051, 10 Tests 

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 š brownish pink/green

Ambient Operating Conditions

Temperature: 0 to 50 °C

Absolute Humidity: 2 to 20 mg H2O / L

Reaction Principle

5 CO + I2O5 š 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
