Temtop M2000C Overview
The Temtop M2000C is a premium CO2 monitor that tracks CO2, PM2.5, PM10, Temperature and Humidity. It uses a NDIR sensor — the technology we recommend for reliable CO2 readings — with a stated accuracy of ±75 ppm across a 0-5000 ppm measurement range. At $160, it is aimed at home use and offices.
In day-to-day use, the M2000C offers an onboard display, so you can read levels at a glance without opening an app, plus USB connectivity for logging trends and setting alerts, plus a stationary design (USB powered) best suited to continuous monitoring in a fixed location.
