Temtop M2000 2nd Generation

Temtop Professional Air Quality Analyzer & CO2 Monitor Particle Counter | M2000 2nd, PM2.5 PM10 Formaldehyde, Temperature & Humidity, Audio Alarm, Data Export for Indoor Analysis

In Stock

Handheld air quality analyzer that pairs a SenseAir NDIR CO2 sensor (0–5000 ppm) with formaldehyde, PM2.5, PM10, temperature and humidity readings on a color TFT screen. It logs more than 3 months of data for USB export and has adjustable audio alarms. Its 3000 mAh battery is the largest listed, yet its 8-hour runtime is the shortest, so it suits spot checks and air quality testing more than all-day monitoring in a van.
