A carbon dioxide sensor or CO 2 sensor is an instrument for the measurement of carbon dioxide gas. The most common principles for CO 2 sensors are infrared gas sensors and chemical gas carbon dioxide is important in monitoring indoor air quality, the function of the lungs in the form of a capnograph device, and many industrial processes.

Carbon Dioxide Sensor Meter 9999ppm CO2 Temperature RH Measurement(190) The portable Co2 and air quality meter is ideal for labs where measuring the environmental conditions is pivotal. The instrument is powered by 6 AAA batteries and can measure up to 9999ppm.

The E+E CO2 sensors feature the dual wavelength/dual detector NDIR principle. One detector is tuned to µm wavelengths, which is absorbed by CO2, the second detector on µm, which is not affected by any gas. For every single measurement the CO2 concentration is calculated from the outputs of …

CO2 Sensors will automatically regulate fresh air delivery so that overventilation does not occur. In fact if fresh air is being delivered from another location such as an open window, hallway or another unoccupied classroom, the sensors will react to this source of …

NDIR sensors are most often used for measuring carbon dioxide. The best of these have sensitivities of 20–50 PPM. Typical NDIR sensors cost in the (US) 100 to 1000 range. NDIR CO 2 sensors are also used for dissolved CO 2 for applications such as beverage carbonation, pharmaceutical fermentation and CO 2 sequestration applications.
