The E-SAMPLER is the most feature-packed light-scatter Aerosol Monitor available. Manufactured by Met One Instruments , whatever your monitoring needs, the 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 gravimetric filter methods. 

The E-SAMPLER provides real-time particulate measurement through  near-forward light scattering principle. 


Every E-SAMPLER is factory calibrated using polystyrene latex spheres. User can conduct gravimetric analysis with 47mm sample filter and use the results to regularly audit and calibrate the real-time measurement. With dual technology E-Sampler is capable of delivering accuracy similar to the reference method.
