NextPM Advanced

Designed specifically for air quality measurement in ventilation ducts and HVAC systems.

NextPM Advanced - OEM Module

The NextPM Advanced replaces the internal fan with an end piece that connects to an external pump. This design ensures stable operation under significant pressure differences, delivering reliable Particulate Matter (PM) monitoring in demanding HVAC environments. The sensor provides real-time PM1, PM2.5, and PM10 data in both µg/m³ and pcs/L.

NextPM-Advanced Technology

• 2 Detection Angles
This feature is unique in this category of optical sensors. Gives a better resolution by the discrimination of particles that could have the same signals at 90°.

• Humidity Shield
NextPM features a patented humidity regulation system that maintains the Humidity levels inside the sensor below 60%. This prevents particle swelling and ensures accurate measurements even in humid environments.

• Coarse Particle Trap
Unique feature avoiding the use of an additional physical filter and improving the sensor lifetime by avoiding premature clogging of the flow by blocking particles > 10 µm.

NextPM-Advanced overcomes the Challenges with HVAC PM Monitoring.

Monitoring Particulate Matter (PM) within HVAC systems is crucial for maintaining Indoor Air Quality (IAQ) however, two primary challenges often arise:​

1. Accuracy of PM Sensors:

Achieving precise measurements of particulate matter is essential for effective IAQ management. However, the accuracy of PM sensors can be compromised by factors such as humidity, varying particle sizes, and sensor placement within HVAC ducts. For instance, low-cost particle sensors (LCSs) may exhibit reduced accuracy due to environmental conditions and sensor positioning, leading to unreliable data and potential mismanagement of air quality.

2. Pressure Drop:

Integrating PM sensors into HVAC ducts can present challenges related to pressure conditions. Most sensors rely on small internal fans to draw air into their measurement chambers. However, these fans often struggle to overcome the higher pressure environments typical within HVAC ducts, leading to inadequate airflow through the sensor and compromised measurement accuracy.

Accurate HVAC PM monitoring

NextPM module with the fan replaced by external pump. In the NextPM Advanced model, the traditional internal fan is replaced with an external pump designed to handle the higher pressure conditions typical within HVAC ducts. This enhancement ensures consistent airflow through the sensor, maintaining measurement accuracy and reliability even in environments with significant pressure variations.
