Portable optical laser particle countersOptical particle counters serve the purpose of measuring the light scattering from airborne particles. This instrument offers real time monitoring of particles below .05 cm in diameter. These Optical Particle counters are in use by environmental engineers that need to measure the size distribution of particulate pollutants in combustors & automobiles.  Optical particle counters are also used for measuring efficiencies of particle control equipment and can be used to calibrate other instruments. Industrial hygienists use optical particle counters to sample particles in occupational environments as well as pharmaceutics to size and classify their powdered drugs.

Optical Particle Counters used for Indoor Air QualityFluke 983 optical particle counterA light source is used, and generally laser or laser diode is adjusted, to illuminate a stream of aerosol flowing out of a nozzle. The off-axis from the light beam measures the amount of light scattered from a a single particle by refraction and diffraction. Both the size and the number of particles are measured at the same time. The size of the particle is figured out by the intensity of the scattered light.
