NextPM

The NextPM sensor is a next-generation solution for air quality monitoring, delivering real-time PM1, PM2.5, and PM10 measurements in µg/m³ and pcs/L. Thanks to its patented airflow control and humidity management technology, it provides highly accurate and stable particulate matter data, even in challenging environments with high humidity or pollution. With minimal maintenance and a lifetime of up to 10 years, NextPM is ideal for smart city networks, industrial monitoring, and environmental applications.

With the NextPM Adjusted option, PM2.5 measurements can achieve less than 10% deviation compared to reference instruments.

2026 Update
Independant sensor performance comparison

All scores derived from published, peer-reviewed or institutional data. Select sensors — evidence, summary table and cited sources update dynamically. Every number is traceable to its source document

Scoring methodology — how each axis is calculated
Score summary — active sensors
References cited by active sensors

This comparison compiles data exclusively from independent third-party evaluations. No proprietary data from any sensor manufacturer has been used for scoring. All metrics are traceable to the cited references. March 2026.
