SS21F8_LE Formaldehyde Sensor – Enhanced Accuracy with Low Ethanol Cross-Sensitivity
SS21F8_LE is a high-performance electrochemical sensor designed to measure formaldehyde concentrations from 0 to 10 ppm.
With ethanol cross-sensitivity ≤3%, and 0% to other gases such as ammonia, carbon monoxide, and acetaldehyde,
it offers superior accuracy for indoor air quality applications compared to standard HCHO sensors.
The sensor provides a linear output of 60 ± 20 nA/ppm, rapid T90 response under 30 seconds,
and ultra-high resolution of ≤0.01 ppm.
It operates from -10℃ to +40℃ with an expected lifetime of over 24 months in air,
making it ideal for integration into air purifiers, indoor environmental monitors, and portable devices.
