In the particles of soot concentration measuring device in the gas which measures the particles of soot concentration in the gas to be measured from Mie scattering light which is generated by
PROBLEM TO BE SOLVED: To provide an apparatus for measuring a dust concentration stably measuring the dust concentration in a measurement gas for a long time.;SOLUTION: The apparatus for measuring the dust concentration includes: a laser device 13 for irradiating a measurement gas 12 with a laser beam 11; a first light detector 31 for measuring generated Mie scattered light 30; and a second light detector 18 for measuring generated Raman scattered light 15. The apparatus measures a signal intensity (=M0) of the Mie scattered light by the first light detector 31 and a signal intensity (=R0) of the Raman scattered light 15 of a gas for concentration correction in a measurement area by the second light detector 18 in advance, measures a detection signal intensity (=M1) of the Mie scattered light by the first light detector 31 and a signal intensity (=R1) of the Raman scattered light 15 of the gas for concentration correction in the measurement area by the second light detector 18 upon correction of a dust concentration, calculates a dust concentration (M2) by multiplying the value M1 by a correction coefficient (K) defined as R0/R1.;COPYRIGHT: (C)2010,JPO&INPIT
