PCE-PCO 1 Particle Counter Dust Measuring Device
Handheld laser particle counter for monitoring cleanroom particulate concentrations, indoor air quality and exposure to dust

This is a handheld laser optical particle counter, or dust particle measuring device, for measuring the concentration of particles in the air. The dust particle measuring device is ideal for monitoring cleanrooms, indoor air quality, exposure to exhaust, tobacco or cigarette smoke and other harmful air pollutants, and levels of airborne dust. Cigarette smoke particles mainly are distributed in the size range from 0.1 to 1.0 micron.

A variety of materials are explosible in dust form. Some examples include: food (e.g., candy, sugar, spice, starch, flour and feed), grain, tobacco, plastics, wood, paper, pulp, rubber, pesticides, pharmaceuticals, dyes, coal and metals (e.g., aluminum, chromium, iron, magnesium and zinc). These materials are used in agriculture, chemical manufacturing, pharmaceutical production, furniture, textiles, fossil fuel power generation, recycling operations, metal working and processing (including additive manufacturing and 3D printing) and many other industries and processes.

In addition to being a combustion hazard, certain kinds of dust can be a health hazard. Exposure (such as skin contact, eye contact and inhalation) can be linked to sneezing, a stuffy or runny nose, itchy or red eyes, headaches, fatigue, fever, cough, shortness of breath, dermatitis, asthma, bronchitis, pneumonia (e.g., Legionnaires’ disease and hypersensitivity pneumonitis) and cancer.
