SFA40
UpcomingMiniature, low power consumption formaldehyde sensor for indoor air quality applications
SFA40 builds on the market success of its predecessor, SFA30, offering ultra-high selectivity to formaldehyde and long lifetime. It features unprecedented low power consumption and top performance – all in a miniature form factor. Engineered in Switzerland, it is designed for easy integration into air purifiers, indoor air quality monitors and air conditioners. All SFA40 sensors feature a digital I2C interface and are calibrated for accuracy at our manufacturing facility in Switzerland.
