Opis izdelka
The Vaisala GMW90 Series is specifically designed for demand-controlled ventilation and HVAC applications. It measures carbon dioxide (CO₂) and temperature, with optional relative humidity measurement. The transmitters are available with either a display opening or a closed front cover, and can include an optional CO₂ traffic light indicator.
Using the latest Vaisala CARBOCAP® sensor technology, the devices deliver excellent long-term stability and reliability. The innovative Microglow infrared light source ensures accurate CO₂, temperature, and humidity measurements with low power consumption and minimal self-heating.
The series is designed for fast installation and easy maintenance. The electronics can be mounted onto a pre-installed backplate, protecting the sensor during construction phases. Configuration and servicing are user-friendly, thanks to DIP switches and easily accessible interfaces.
Interchangeable measurement modules allow for quick on-site calibration or easy replacement with factory-calibrated spare modules. Each unit is delivered with a traceable 3-point CO₂ calibration certificate.
