General Description
The E-SAMPLER is a dual technology instrument that combines real-time measurement of light scatter with the standard of filter methods for monitoring PM1.0, PM2.5, PM10 and TSP (Total Suspended Particles). Filters can be extracted and replaced in less than one minute and filter medium can be selected based on laboratory analysis.
Principle of Operation
E-SAMPLER provides real-time particulate measurement through near-forward light scattering. An internal rotary vane pump draws air at 2 LPM into the sensing chamber where it passes through visible laser light. Aerosols in the air scatter light in proportion to the particulate load in the air. Scattered light is collected by glass optics and focused on a PIN diode. Rugged state of the art electronics measure the intensity of the focused light and output a signal to the CPU.
