PURPOSE: An apparatus for loss measurement by particle deposition in a sampling conveyance pipe is provided to increase reliability of measurement by implementing continuous monitoring. CONSTITUTION: A light source generation unit(14) is installed in the outside of a pipe direct-coupled type particle counter. The light source generation unit irradiates light perpendicular to an axial direction of a conveyance pipe(10). A photometer(15) is installed in the same plane as the light source generation unit. The photometer measures a degree of scattering of light generated by sample particles. A calculation and signal processing unit(16) calculates the number of particle samples.
