NDIR CO2 and laser PM2.5, in one mid-priced monitor
Temtop appears in one family here: air quality monitors.
Two named sensor technologies. NDIR for CO2 and a laser sensor for PM2.5/PM10 — both disclosed explicitly, a rarer combination in this family than a single vague “air quality” reading.
Data export via USB/CSV, letting readings be logged without a mandatory app or account — a middle ground between the TFA Dostmann’s no-logging design and the Airthings’ app-only approach.
A rechargeable battery, rather than the TFA Dostmann’s USB-tethered design or the Airthings’ AA-battery/USB setup.
CO2 + PM2.5/PM10 · NDIR + laser sensor · rechargeable
A handheld multi-pollutant monitor combining an NDIR CO2 sensor with a laser particle sensor for PM2.5 and PM10, alongside temperature and humidity. Readings show on a color TFT screen, with an audio alarm and CSV export over USB — no Wi-Fi or companion app.
Best for: Anyone who wants CO2 and particulate readings together in one portable unit, and is comfortable exporting data manually rather than watching it in an app.
