The Met One Instruments MCERTS Laser Backscatter Particulate Monitor (Model E-Sampler) is a light-scatter aerosol Monitor. Whatever your monitoring needs, the feature-packed E-sampler will provide accurate, dependable and relevant data. The E-Sampler is a dual technology instrument that combines the unequalled real time measurement of light scatter with the accuracy standard of filter methods. The simple filter loading process testifies to the seamless blending of both technologies.

How it works

The 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 precise 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. The output is linear to concentrations greater than 65,000 ug/m3 . Every E-Sampler is factory calibrated using polystyrene latex spheres of known index of refraction and diameter at multiple points to validate linearity.
