Carbon monoxide
Where is it found?
CO is found in fumes produced any time fuel burns in cars or trucks, small engines, stoves, lanterns, grills, fi replaces, gas ranges, or furnaces.
Improperly ventilated appliances and engines, particularly in a tightly sealed or enclosed space, may allow carbon monoxide to accumulate until dangerous levels.
Why is it harmful?
Carbon monoxide or CO is an odourless and colorless pollutant gas that can cause death. When CO is inhaled into the body, it mixes with the blood avoiding the oxygen absorption.
The CO exposure of a person over a certain period of time can cause illness and even death.
CO cartridge
The Carbon Monoxide Cartridge has a built-in electrochemical sensor with very low noise electronics allowing the measurement from very low concentrations (ppb) up to several ppm. To cover different applications, there are two measurement ranges: Type A measuring most common concentrations range, and Type B, a higher range version that can measure up to 500 ppm, decreasing the accuracy at low concentrations.
This cartridge is very stable over time with a lifespan that can go beyond the specifi – cation for several months under no extreme environments.
