GMW83 HVAC Temperature and CO2 Sensor for DCV. Wall Model, Voltage outputs.

The Vaisala GMW80 series CARBOCAP® carbon dioxide and temperature transmitters are wall-mount transmitters designed to fulfill the needs for CO2 measurements in standard demand controlled ventilation (DCV) and Indoor air quality monitoring (IAQ). The CO2 measurement is based on a second generation CARBOCAP® sensor, which uses a novel, silicon-based microchip emitter.

The internal reference in the CO2 sensor guarantees the best stability and operation also in constantly occupied buildings without frequent readjustments.

The CARBOCAP® sensors give correct CO2 measurements immediately when powered on. Proper operation can be verified immediately after snapping on the device cover.
