Carbon Dioxide Sensors
SST Controls provides a wide range of CO2 sensors for almost all applications.
With 20Hz sampling options for Modified Atmosphere Packaging (MAP) and medical capnography our sensors provide reliable measurements in difficult applications.
Our low power sensors are suitable for battery operated systems within Indoor Air Quality (IAQ), horticulture, aerospace, CO2 storage, and food transportation.
Automatic calibration provides a fit and forget sensor for offices, schools, hospitals and public buildings as stand-alone or linked to BMS systems.
