‘Feel-Good Climate’ with Energy Efficiency

Air, Gas and Liquid Control with Measuring Devices from S+S

Our Sensors for Air Quality and Flow

Increased indoor CO2 values, fine dust (PM) or VOC loads are bad for
energy efficiency and well-being. With our AERASGARD air quality and RHEASGARD ­flow sensors you can monitor the entire room climate in a controlled way. And with our RHEASREG flow monitors and controllers
you are well in control of ducts for air, gases or liquids.

Application Areas of Air Quality Measuring Devices

Room ventilation and air-conditioning, flow monitoring of ventilators,
butterfly valves, heating registers and humidifiers, energy management, residential, working and conference rooms, movie theatres, showrooms
and retail stores, institutes and laboratories
