Six channels and particle size range of 0.3 – 10.0 µm Ultra-lightweight and ergonomic design Long battery life Large 3.5 QVGC Color display 10,000 record storage On-screen data presentation Personalized setting and configurations Data export options The principle of airborne particle counters. The particle crossing the illumination zone produces a photoelectric impulse, which is connected with the size of the particle to be measured. Calibration curves calculated by us using Mie theory for different scattering and integration angles are shown in Fig.
Particle Counters Monitor Fine Particulates for Cleanroom Manufacturing, Sensitive Production, and HVAC Systems. Airborne particle counters play a crucial role in monitoring, classifying, and diagnosing the source and complexion of contaminants in cleanroom operations. 3.2 state the postulates of the particle theory of matter (all matter is made up of particles; all particles are in constant motion; all particles of one substance are identical; temperature affects the speed at which particles move; in a gas, there are spaces between the particles; in liquids and solids, the particles.
Particle counters display readings in two columns: cumulative (often depicted by ∑ sigma) and differential (often depicted by ∆ delta). The cumulative total shows the amount of particles that were found at that size and greater. False Count Rate or zero-count rate is defined as the number of false counts recorded by an air particle counter with respect to time. False particles are associated with the number of intrinsic and extrinsic sources to the system such as cosmic radiation, optoelectronic noise or contamination.
