GMW90

GMW90 Series Carbon Dioxide, Temperature, and Humidity Transmitters

 

The wall-mounted Vaisala GMW90 Series CARBOCAP® CarbonDioxide, Temperature and Humidity Transmitters are intended fordemand controlled ventilation applications. They measure carbondioxide and temperature and have an option for an additionalhumidity measurement.

GMW90 in brief:

  • A flexible CO2 transmitter family with a variety of options andfeatures
  • Both analog and digital output models available
  • Comes with a calibration certificate
  • Easy installation due to well-designed features such as snap-onelectronics, dip switches, and display
  • Convenient calibration: Choose either a field exchangeablemeasurement module or calibrate using a hand-held meter or areference gas bottle.

GMW90 family includes the following models:

  • GMW93(D) CO2+T,  voltage output (with display)
  • GMW93R(D) CO2+T+RH, voltage output (with display)
  • GMW93RA CO2+T+RH , voltage output with CO2 indicator LED anddisplay
  • GMW94(D) CO2+T, current output (with display)
  • GMW94R(D) CO2+T+RH, current output (with display)
  • GMW95(D) CO2+T, digital model (with display)
  • GMW95R(D) CO2+T+RH, digital model (with Display)
