CO2 Sensors Products |

Indoor and outdoor air has between 400ppm and 2,000ppm CO2 by volume. This means that for projects from measuring indoor air quality to measuring atmospheric CO2, a 0-1% (0-10,000ppm) CO2 sensor is your best solution. For applications like CO2 alarms in restaurants, breweries, or around stored CO2 tanks, a 5% CO2 sensor is used.

Why is hydrogen such a big issue for CO sensors? | GfG ...

The third chart compares the performance of the GfG 2CF hydrogen nulled sensor, and a standard GfG 4CM CO sensor exposed to 200 ppm CO calibration gas. While the hydrogen nulled sensor takes a little more time to recover after exposure, the time to alarm is virtually the same for both sensors. What other gases and vapors can have an interfering effect on CO sensor readings? Although the ...

How does an Oxygen Sensor Work? -

Carbon monoxide, if present in the test gas, is oxidized by O2 to form CO2 and thereby triggers the flow of current. The zirconia sensor does not directly sense O2, but rather the difference between the concentration of O2 in the exhaust gas and in the normal air. While zirconia oxygen sensors are most commonly used in cars to control air-fuel ratios, they are also important in industrial ...

Carbon Monoxide Levels Chart -

Carbon monoxide exposure is the most common method of death by poisoning in the world. The effects of carbon monoxide poisoning are well understood. CO gas competes with oxygen to bind with hemoglobin in the blood leading to a reduction of oxygen in the brain. Even low carbon monoxide levels over long periods can have an impact on brain chemistry.
