Model HRH-AMC01 Aerosol Concentration Measuring Unit is mainly used to measure concentration of aerosolized substances, especially for real-time particle concentration measurements (mg/m3). With features of portable and removable probes, it can work in hard-to-reach areas, not only suitable for fixed sites but also for general measurement applications. Adopted near-forward light scattering principle, it can perform accurate and repeatable measurements of aerosol concentration.
