Model T640 PM Mass Monitor

The Model T640 delivers 1-min or better time resolution with exceptional sensitivity and precision. The instrument is very low maintenance and requires no sample media for minimal cost of operation.

The T640 is an optical aerosol spectrometer that converts optical measurements to mass measurements with sharp accuracy by determining sampled particle size via scattered light at the single particle level according to Lorenz-Mie Theory.
