Series Description
The Vaisala GMW86 and GMD20 Series Carbon Dioxide Sensors with transmitter capabilities are specially designed for demand-controlled ventilation in building automation systems, BAS. The CO2 transmitters use the silicon-based CARBOCAP gas sensor. The simple structure and reference measurement capabilities make these single-beam, dual-wavelength NDIR CO2 sensors extremely stable and reliable. The temperature and flow dependence is negligible. Models are available with a temperature output.
