These CO detectors sense and transmit carbon monoxide levels, for use in any industrial or commercial indoor environ­ment where accurate CO detection is required, i.e. parking.

Such information is crucial to demand controlled ventilation that ensures adequate indoor air quality while minimizing the energy costs of conditioning outside air. Uses an electrochemical sensor, Output signal: 4 – 20 mA, 0 – 5 VDC or 0 a 10 VDC proportional to the measured value.
