Sensor for measurement of carbon dioxide (CO2) concentration in the air with excellent accuracy, for concentrations of 0 – 2000 ppm, NDIR sensor type. It is intended for connection with Papago TH CO2 ETH only.
CO2 sensor is ideal for applications where accurate CO2 levels need to be measured and controlled for indoor air quality and energy saving applications such as demand control ventilation.
