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. 5-year warranty is valid for instruments purchased in 2021 and beyond.

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 designed for standard, demand-controlled ventilation applications. The GMW80 is ideal for buildings occupied 24/7.

The CO₂ measurement of the GMW80 series is based on a second-generation CARBOCAP^® sensor, which uses a novel, microglow light source instead of an incandescent light bulb for a longer trouble-free lifetime. 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 as they have a built-in reference measurement. Proper operation can be verified immediately after snapping on the device cover.

The following product models are available: GMW83RP, GMW83DRP, GMW83, GMW83A, GMW83D, GMW84, GMW84S, GMW87 and GMW88.
