Formaldehyde CH2O smart sensor

The SEN-SMT-HCHO-L smart DirectSense II Formaldehyde sensor is ideal for the low (0 to 1000ppb) IAQ range, with an excellent L.O.D. (<10ppb). Unlike most EC HCHO sensors, this sensor exhibits negligible CO cross-sensitivity <10ppm CO (GrayWolf meters alert when >10ppm CO might influence readings whenever a CO sensor is also installed in the DSII probe).
