Our take
The M2000 is a meter you carry rather than a monitor you leave on a shelf. Walk it from room to room, hold it by the window, check the new sofa for formaldehyde: it reads particles, CO₂ and HCHO in one.
Its NDIR CO₂ sensor is the accurate type, and the logging and export make it useful for anyone who wants their own records.
The M2000C 2nd is a similar model without formaldehyde. Check the name on the listing.
Good for
- Checking several rooms, or a classroom or office
- Formaldehyde from new furniture or flooring
Skip it if
- You want app alerts: it's a standalone meter
