Carbon Monoxide 50/a-D (50-600 ppm)
Application Range | |
Standard Range | Measurement Time |
50 to 600 ppm | 1 h |
25 to 300 ppm | 2 h |
10 to 120 ppm | 5 h |
0.25 to 75 ppm | 8 h |
Standard Deviation | ± 20 to 25 % |
Color Change | yellow - grey black |
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.
