CO2, Temperature and Humidity Transmitter Series GMW90

The wall-mounted Vaisala GMW90 Series CARBOCAP® Carbon Dioxide, Temperature and Humidity Transmitters are especially suited for green building projects. The devices measure carbon dioxide and temperature and have an option for an additional humidity measurement. The instruments come with a calibration certificate that meets traceability and compliance requirements. Traceablity is easily maintained with field-exchangeable intelligent measurement modules. The transmitter can be blended into the interior design of the space where it is installed using the optional decorative cover.

Key Benefits

Easy installation
The GMW90 Series Transmitters have been designed for quick and easy installation. Every model includes a display for easy startup. To protect the sensor from dust and dirt during construction and installation, the units can be cabled with back-plate only. Electronics can be snapped on later at an appropriate phase in the construction project. This saves installation time in the project.
Convenient calibration
Regular instrument maintenance guarantees a long product lifetime although the transmitter’s inspection interval is five years. Calibration is easiest using the exchangeable measurement modules. Sensor traceability and measurement quality is easily maintained by snapping on a new module calibrated at Vaisala factory. The instrument can also be calibrated using a hand-held meter or reference gas CO2 bottle. The service interfaces are easy to reach by simply sliding the cover down. The closed cover keeps the measurement environment stable during calibration and ensures a top-quality final result.
