PARTICLE COUNTER FOR MEASURING PPM(PARTS PER MILLION) OR PPB(PARTS PER BILLION) LEVEL THE NUMBER OF MINUTE PARTICLE

摘要

PURPOSE: A lens unit of n prepares guides the respective light to the flow tube of n, and the sensor of n and the flow tube of n. While numbering the minute particle which is flown to the flow tube of n, the measurement time can be shortened about 1/n.;CONSTITUTION: A particle counter comprises a light source(10), n fluid pipes(30), n detecting units(50), and a plural lens parts(70). In n fluid pipes, the light rayed from the light source is transmitted. In n fluid pipes, the fluid in which the measurement target minute particle is contained flows with n passenger. It leaves n fluid pipes about the light source in interval and n detecting units is arranged. In n detecting units senses n quantity of light n fluid pipes transmitted. A plurality of lens units is arranged between n detecting units of and the light source. A plurality of lens units guides the light rayed from the light source to n fluid pipes and n detecting units.;COPYRIGHT KIPO 2012
