NextPM sensor - particulate matter

NextPM sensor is the most advanced particle measurement solution available on the market

Providing real-time PM1, PM2.5, and PM10 measurements in both µg/m3 and pcs/L, compared with some alternatives which are only able to estimate PM 2.5 and PM 10. It can detect particle concentrations in the range of 0 to 1000 µg/m3 and between 0.3 and 10 µm in diameter.

With its patented air flow control technology, NextPM can deliver up to 10,000 hours of monitoring without the need for maintenance or calibration and boasts the most competitive cost of operation on the market thanks to its low power consumption, typically less than 80mA in operation.

High Accuracy

Due to its proprietary optical architecture and TERA Sensor unique algorithm, the NextPM is the best sensor to size particles. For this kind of technology, an effective sizing is the former key to a precise PM measurement.

Cost efficiency

With 10 000 hours without maintenance, NextPM offers optimal costs of ownership by reducing maintenance operations.

Quality products for teraQuality product

Each part of NextPM has been specifically designed, crafted and tested by our team based in France in order to meet the highest quality standards and provide the most reliable technology.
