A key strength of the M2000 is its high-quality sensor suite, drawn from respected sensor manufacturers to ensure dependable, accurate measurements. It employs a Temtop laser PM sensor for particulate detection, a SenseAir NDIR sensor for CO2, a Dart sensor for HCHO and a Sensirion sensor for temperature and humidity. This combination of proven technologies allows the device to deliver trustworthy data across all of its parameters, giving users confidence in the readings whether they are checking ventilation effectiveness, identifying pollution sources or verifying indoor comfort.

• The M2000 covers practical, real-world measurement ranges.
• Particulates are measured from 0 to 999 ug/m3 with 0.1 ug/m3 resolution, with PM2.5 accuracy of +/-10 ug/m3 (0-100) or +/-10 percent above 100, and PM10 accuracy of +/-15 ug/m3 (0-100) or +/-15 percent above 100.
• CO2 is measured by NDIR across 0 to 5000 ppm with +/-(50 ppm + 5 percent of reading) accuracy, HCHO across 0 to 2 mg/m3 (with a limit of 5 mg/m3) at 0.001 mg/m3 resolution, temperature from 0 to 50 C and humidity from 0 to 90 percent RH.
• Together these ranges cover the conditions encountered in homes, offices, schools and many field environments.

• Usability and data capture are central to the design.
• A clear colour TFT screen presents all parameters at once, complete with a histogram view that helps users visualise trends and fluctuations over time rather than relying on a single instantaneous reading.
• A settable audio alarm draws attention when pollutant levels exceed chosen thresholds, prompting timely action such as increasing ventilation or removing a pollution source.
• For record-keeping and analysis, the M2000 supports USB data export in CSV format, allowing readings to be transferred to a computer for reporting, comparison and documentation.

Portability and convenience make the M2000 practical for everyday and professional use. It is powered by a 3000 mAh rechargeable battery providing approximately 6 to 8 hours of operation, with charging via a DC 5V, 1A input, so it is ready for extended measurement sessions and field surveys. Its compact dimensions (73.5 x 223.5 x 37.5 mm) make it easy to hold and carry between rooms or sites, while CE and FCC credentials reflect its compliance with recognised safety and electromagnetic standards.

For buyers, the M2000 offers professional multi-parameter sensing in an affordable, portable package, combining quality sensors, clear visualisation, alarms and data export. It is an ideal choice for anyone who wants to monitor and improve indoor air quality with confidence and convenience.
