Siro-CO2

Multifunctional CO2 transmitters for building automation systems

Siro-CO2 is a carbon dioxide transmitter with a modern design and new hardware, including sensors. The transmitter combines CO2 concentration, temperature and optional relative humidity and VOC measurements into one easy-to-use device. It offers easy installation and adjustment, several different model options and various output signals that are configurable separately for each measurement parameter. Siro-CO2 utilizes the industry standard NDIR measurement principle with self-calibrating ABC logic™ for CO2 measurement.

Available in Q1/2021.
