SEN69C

Upcoming

Sensing platform for PM, RH/T, VOC, NOx, CO2 and HCHO measurements

Experience the future of air quality sensing with the compact and powerful SEN69C. It combines multiple sensors in a never-before-seen form factor and can measure up to ten environmental parameters (PM1, PM2.5, PM4, PM10, T, RH, VOC Index, NOx Index, CO2, HCHO). The innovative design simplifies integration, reduces costs, and allows for customization. At the core of the SEN69C is a brand-new, miniaturized, MEMS-based particulate matter sensing component – the SPS6x.

 

Applications requiring compliance with IAQ standards, such as RESET® and WELL Building Standard™, are well served by the SEN69C (CO2 not compliant, see SEN66 instead).
