Main characteristics

1. zero error alarm rate

2. real time response

3. data accuracy

4. minimum resolved particle size of 0.3 microns


PMSX0XX series is a digital universal particle concentration sensor, can be used to obtain a single

The number and mass of suspended particles in the air in a position, that is, the concentration of particulate matter, and the number of the particles in the air.

Port form output. This sensor can be embedded in a variety of airborne particulate matter concentration associated with the instrument

To provide timely and accurate concentration data for the instrument or environment.

Working principle

The sensor adopts the principle of laser scattering. Even if the laser irradiation suspended particles in the air.

At the same time, the scattered light is collected at a certain angle, and the scattered light intensity changes with time.

Chemical curve. Then use the microprocessor (MIE) based on Mie theory algorithm, obtained a

Particle size and number of particles with different particle sizes in the unit volume.
