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), 10ppm CO can still be measured in the presence of 10000 ppm n-octane.
