CO2, Humidity and Temperature Transmitter Series GMW80

Measuring CO2 is the most economical way to monitor both indoor air quality (IAQ) and human presence with one sensor. Inadequate ventilation results in elevated CO2 levels, causing drowsiness and decreased productivity. Good indoor air quality can be achieved based on occupancy levels. Energy is saved by minimizing the use of unconditioned outside air.

For accurate and stable HVAC measurements, the wall-mounted Vaisala CARBOCAP® Carbon Dioxide and Temperature Transmitter Series GMW80 provides the best stability and reliability on the market, up to 15 years. These indoor air quality sensors are designed for standard, demand-controlled ventilation applications. The GMW80 is ideal for buildings occupied 24/7.
