Airborne Particle Counter Procurement Questions

Q1: What is the working principle of an airborne particle counter?  A: Airborne particle counters work based on the laser light scattering principle. When laser irradiates suspended particles in the air, light scattering occurs. The larger the particle surface area, the stronger the scattered light. The instrument captures light signals, performs photoelectric conversion and calculation, counts particles of different sizes per unit volume, and determines the cleanliness class. HJCLEAN’s online monitoring systems, portable desktop and handheld particle counters all adopt this proven technology for stable and reliable measurement.
