The Vaisala Carbon Dioxide (CO₂), Humidity and Temperature Transmitter 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.

for smart control of biogas quality

Get more value out of waste by improved decision-making, and by reducing your operating costs. Vaisala CARBOCAP® MGP261 Multigas Probe for Methane, Carbon Dioxide and Humidity helps in improving your process and in protecting the Combined Heat and Power (CHP) engine. The MGP261 probe is compact in size, Ex certified, and can be installed directly into the gas line without the need for sample treatment.
