Handheld Dust Particle Counter

Introduction:

A handheld particle counter is a portable device designed to rapidly measure the number and size distribution of dust, particulate matter, and other small particles in the air. These instruments are widely used in various industries, including but not limited to pharmaceuticals, semiconductor manufacturing, hospitals, cleanrooms, and air purifier effectiveness verification.
