Handheld dust particle counter

；

Introduction:

Handheld dust particle counter is a portable detection device specially designed for rapid measurement of the number and size distribution of dust, particulate matter and other tiny particles in the air. Such instruments are widely used in many industries, including but not limited to pharmaceuticals, semiconductor manufacturing, hospital operating rooms, dust-free workshops, air purifier effect verification and other fields.
