GMD110

CO2 Transmitter Duct Model GMD110 For high-accuracy measurements in HVAC applications

The duct-mounted high-accuracy transmitter GMD110 is designed to measure carbon dioxide in demanding HVAC applications. The IP65-rated transmitter is equipped with the renowned CARBOCAP® sensor: Its structure and reference measurement capabilities make this single-beam, dual-wavelength NDIR sensor extremely stable and reliable. CO2 concentration is measured inside the duct without risks for leaks or wrong flow direction affecting the measurement. The measurement accuracy is not affected by dust, water vapor or chemicals.

Features:

• ± 40 ppm CO2 accuracy
• Traceable calibration (certificate included)
• Incorporates Vaisala CARBOCAP® sensor
• Analog and Modbus RTU output options
• Excellent long-term stability
• Optimal choice for demand-controlled ventilation

Key benefits:

• High precision: CO2 concentration is measured inside the duct without risks for leaks or wrong flow direction affecting the measurement. The measurement accuracy is not affected by dust, water vapor or chemicals either.
• Stability - Reliability: The high quality and excellent stability of the measurements enables precise and reliable controls of HVAC systems, even in demanding conditions or sites.
• Traceable Accuracy: The instruments are individually adjusted and delivered with a traceable (ISO 9001) calibration certificate. The transmitter is easy to calibrate also on site using a Vaisala handheld meter or Vaisala Insight PC software.
• Fit for demanding measurement needs: Vaisala provides a wide range of HVAC transmitters to complement the building automation system even in the most demanding indoor environments and their control needs – data centers, other industrial buildings, hospitals, cleanrooms; or monitoring and control of indoor environmental quality in any space where health security matters.
