Symaro air quality –
energy efficiency and more comfort

Unique product range with stable measurement method
The air quality sensors cover all requirements and are suitable for every type of building. The high-precision multisensors (CO₂/VOC 1), CO₂/T and CO₂/T/r.h.) are available for room and duct applications, and also with an attractive display.
Efficient in usage
Through infrared absorption measurement (NDIR), air quality sensors determine the CO₂ concentration. And because of an additionally integrated reference light source, they can also periodically recalibrate themselves. This ensures freedom from maintenance, long-term stability and maximum measuring accuracy. The sensors also deliver immediately, precisely measured values regardless of room occupation. Ultimately, you save substantial start-up, service and operating costs.
Comfortable and economical installation in the air duct
Fast, secure and cost-efficient installation – with no need for additional duct installation housing or sealing measures: The installation of air duct sensors is very easy thanks to their ergonomic, installationfriendly housing. Due to the infinitely variable immersion depth, the sensors can be optimally adapted to every installation situation. Additionally, because of the patented measurement system, alignment with the flow direction is no longer needed. Two totally separate chambers for measurement modules and connection terminals prevent air outside the duct from affecting the measurement accuracy.
Energy-saving room comfort
Optimum air quality with low energy consumption: Combined with systems from Siemens, controllers and variable speed drives, Symaro air quality sensors allow for optimized demand-controlled ventilation 2). Thus, 20 to 70 percent in energy and cost savings can be achieved.
