Carbon Monoxide 50/a-D (50-600 ppm)

Ambient Operating Conditions

Temperature	10 to 25 °C
Absolute Humidity	3 to 15 mg H₂O / L

Reaction Principle

CO + Pd-Salt - CO₂ + Pd

Cross Sensitivity

There is no interference during a 4-hour measurement by:

100 ppm ammonia
4 ppm sulfur dioxide
25 ppm nitrogen dioxide
2,000 ppm n-butane

Following a 4-hour exposure, 20 ppm hydrogen sulfide simulates an indication of approximately 50 ppm x h carbon monoxide.
