Updated CO2 detector provides real-time measurements of air quality index, including CO2, PM2.5, PM10, number of particle, formaldehyde (HCHO), temperature and humidity. 

It features a histogram function to display PM2.5 concentration changes in the latest 12 hours. Built-in 70000 sets of data storage capacity and CSV reports can be directly exported to your PC by using USB cable.

M2000 2nd will automatically alert you through buzzer or indicator when levels get too high.

This product is fast-responding and sensitive. It uses a American Temtop PM sensor, a Swedish SenseAir NDIR CO2 sensor, a British Dart formaldehyde sensor and a Swiss Sensirion Temperature & Humidity sensor.

The calibration function for CO2 and HCHO sensors are also available to sustain a better performance under various scenarios.

Our M2000 Series air quality monitoring devices have successfully passed AQMD's rigorous certification testing, reinforcing their reliability and quality.

Measures PM2.5, PM10, particles, HCHO(formaldehyde), TVOC, AQI, temperature, humidity, and histogram function.

Temtop advanced third-generation laser particle sensor has a lifetime of up to 20,000 hours. Combined with the unique particle swarm optimization algorithm, it makes particle measurement more accurate and stable.
