NextPM – Particulate Matter Sensor
OEM gas sensor with state of the art sensing technology.
NextPM sensor is the most advanced particle measurement solution available on the market
NextPM has been designed to meet the very highest performance standards in all applications. Featuring advanced technical specifications that enable ultra-precise measurements to be obtained, even in extreme climatic conditions.
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.

FAQs
The NextPM has the ability to automatically trigger and regulate its internal heater in case of high relative humidity. This provides a better measurement accuracy in those specific environmental conditions by drying the input air and the particles.
To extend the lifetime of the device, we recommend placing a metallic grid at the inlet of the NextPM to avoid insects or dust getting in the sensor. Please get in touch for more details.
If the integration is difficult, you add a duct made with antistatic materials and with an internal diameter of 9 to 10 mm (depending on the rigidity of the material). The maximum length of the duct must not exceed 100 cm to avoid particle losses in the tube, and approximative measurements. Avoid sharp angles in the tubings as much as possible to prevent particle losses and approximation in measurements.
Yes, the sensor is already calibrated. There are 3 levels of calibration available. Please get in touch for more details.
