Infrared Gas Sensor Identifies CO2

The model 6003 CO₂ sensing module includes a gold-plated optical sensing element and all of the electronics necessary to provide a calibrated digital signal output. Measuring only 2" x 2.25" x 0.8" and consuming merely 45 mA, the sensor can be configured to measure concentrations from ppm levels up to 5%. All units are factory calibrated and ready for integration. Flow-through or diffusion sampling versions are also available. This model also features the company's patented self-calibration algorithm that is claimed to eliminate the need for on-going calibration in most applications.
