CO-9400 Youshiko Air Quality Monitor with Wireless PM2.5 / PM10 Sensor

The Youshiko CO-9400 tracks PM2.5 and PM10 particulate matter, the fine and coarse dust that standard weather stations do not measure, alongside indoor temperature, humidity and an MSF radio controlled clock. A wireless sensor with a high-precision laser scattering system takes the readings and sends them to the console.

Why Choose This Air Quality Monitor?

Particulate matter, PM10 and the smaller PM2.5, is small enough to reach deep into the lungs, and levels can be higher than expected in built-up areas or near busy roads. This monitor gives you an ongoing AQI reading and an alert if levels climb, so you know when it is worth keeping windows shut or airing a room out.
