GMW88 HVAC CO2 for Greenhouses and wet areas, Wall model, IP64

The Vaisala GMW80 series CARBOCAP® carbon dioxide 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 applying the power.

The IP64-rated GMW88 model is splash- and dust-proof.
