Protronix NLII-PM2,5

The Protronix NLII-DUST-IQRF sensor is used to monitor indoor air quality and to control HVAC and filtration systems according to the current level of air pollution. The sensor measures the mass concentration of aerosol particles (PM) in the air such as dust and others. It is suitable for schools, offices, shopping centers, homes, restaurants, fitness centers, commercial buildings, operations, etc.

• detects and measures aerosol particles
• two analog outputs 0 - 10 VDC for PM2.5 and PM10
• no maintenance during operation
• longevity and stability

 

Description

The measurement works on the principle of laser beam scattering on particles. Particles larger than 10 μm can already be disposed of by the human body, but finer particles can easily reach deep into the airways and can reach the alveoli and subsequently into the bloodstream.

The sensor is equipped with two analog outputs for PM2.5 and PM10 particle sizes, which are taken as standard indicators of airborne dust pollution. The measurement output of all particle sizes is then available through the communication interface.

With three LED indicators, instantaneous air quality can be easily detected.
