S-CO2, a reliable and accurate device that enables systems to optimize indoor air quality

Indoor air quality can generally be assessed by measuring the concentration of carbon dioxide, known to be representative of indoor air conditions. The S-CO2 is useful in many places (such as schools, office buildings, and private homes) where the concentration of CO2 can vary with the occupancy and use of the rooms. Its technologies ensure long-term stability and performance: the S-CO2 is pre-calibrated to measure, in real time, indoor CO2 concentrations from 0 to 2000 ppm, and it delivers both analog (0-10 V) and digital (PWM) output signals. Thanks to its dual-beam measurement technology, the S-CO2 can be placed in any room, at any time, whatever the installed system. The Aereco CO2 sensor integrates the NDIR technology, a selective auto-calibrated technology that allows a good assessment of the indoor air quality.

S-VOC, a smart sensor for holistic assessment of indoor air quality 

The S-VOC is designed to accurately and reliably assess the level of volatile organic compounds (VOCs) typically associated with cigarette smoke, cooking smells and other pollutants. Using the MOS technology, the S-VOC measures the concentration of VOC and odours at a real time and evaluates the CO2 level of the room (see graph below). Its output signal reports values from 0 to 2000 on a “ppm CO2 equivalent” IAQ scale. This output signal is available simultaneously in two forms: analog (0-10V) and digital (PWM).

S-RH/T, a versatile unit that measures humidity and temperature

The S-RH/T is designed for applications such as demand-controlled ventilation and air conditioning where accurate measurements, excellent long-term stability, and maintenance free-operation are absolute musts. The temperature and humidity measurements are available simultaneously to optimize their contribution to comfort and health.
