Temtop M10 Air Quality Tester AQI PM2.5 Rechargeable TVOC HCHO Real Time Monitor

Gently and infrequently used, in excellent condition. This works great, I just have two other air quality monitors and don't need so many! • The Temtop M10 is able to detect both formaldehyde and VOCs in addition to very fine particles. If you’re concerned about off-gassing from new furniture, or from pressed wood products like particleboard or MDF cabinets, this monitor is a good choice. • Particles can be directly emitted from wind-blown dust, mold spores, pollen and wildfires. Especially during a wildfire, smoke from outdoors can enter your home and make indoor air unhealthy. The Temtop M10 tracks your air quality continuously, so it’s good for use in areas where you want easy access to air quality information, like a workshop, a baby’s room, or next to a gas fireplace. The indicator LED will turn red if the sensors detect dangerous levels of any of the monitored substances. • It's battery-powered, and the included USB cord can be used to power it in addition to charging the battery. • Easy-to-read display, with big numbers and a clear indication of what’s currently being detected.
