The FNIRSI SFD-02 monitors formaldehyde (HCHO) and TVOC levels indoors, which is useful after painting, new furniture or renovation. A 2.4-inch tempered-glass touchscreen shows HCHO, TVOC, humidity and time together.
It grades formaldehyde from excellent to severe, records history, averages readings across a room and lets you set your own alarm thresholds. The electrochemical HCHO sensor warms up in 5 seconds.
