The Vaisala GMD110 is a high-precision duct-mounted sensor for measuring carbon dioxide (CO₂) in ventilation systems and air ducts. It is ideal for demand-controlled ventilation applications and offers excellent measurement accuracy and long-term stability, even under challenging conditions.
Equipped with the proven CARBOCAP® NDIR sensor, the GMD110 delivers highly reliable CO₂ measurements that are not affected by dust, water vapor, or chemicals. By measuring directly in the duct, it avoids errors caused by leakages or incorrect airflow direction.
The sensor achieves an accuracy of ±40 ppm, supports both analog outputs and Modbus RTU communication, and is housed in a robust IP65 enclosure. Each unit is individually calibrated and supplied with a traceable ISO9001 calibration certificate.
For maintenance, on-site calibration can be performed using the Vaisala HM70 or the Vaisala Insight PC software, ensuring long-term measurement reliability.
