SENSOR GMW94RD

The wall-mounted Vaisala CARBOCAP® carbon dioxide relative humidity and temperature transmitter GMW94RD is designed for demand-controlled ventilation applications. It features three 0/4..20 mA analog outputs corresponding to carbon dioxide concentration 0...5000 ppm, relative humidity 0..100 %RH, and temperature range -5..55 °C. Each unit is calibrated and supplied with a traceable calibration certificate. The device has a continuously readable local display. The field-serviceable transmitter can be calibrated if needed by replacing the measurement modules, which are available as spare parts. The GMW94RD transmitters use Vaisala HUMICAP® humidity sensors and next-generation CARBOCAP® technology, whose semiconductor-based internal reference measurement ensures measurement accuracy, long-term stability, minimal drift, long lifespan, and minimizes maintenance requirements. The sensors and transmitter are manufactured in Finland. This product description is an automated translation of the original Finnish description.
