ES-642 REAL TIME PARTICLE MONITOR NEWLY RELEASED!

The ES-642 is a type of nephelometer which

automatically measures real-time airborne PM10,

PM2.5, or TSP particulate concentration levels using

the principle of forward laser light scatter.

Sample air is drawn into the ES-642 and

through the laser optical module, where the

particulate in the sample air stream scatters

the laser light through reflective and

refractive properties. This scattered light is

collected onto a photodiode detector at a

near-forward angle, and the resulting electronic

signal is processed to determine a continuous,

real-time measurement of airborne particulate mass

concentrations
