Abstract

PURPOSE:To realize a high-precision measurement by using a set of two different comparison wave length and absorption wave length to measure water content in a powder material and obtaining actual water from both measurement results on a basis of an expression obtained previously. CONSTITUTION:The light of infrared-ray light source 2 passess through condenser 4 and has the direction changed by reflection mirror 5 and passes through sector 6. The light passed through sector 6 becomes two wave length of 1.8mu and 1.9mu and has the direction changed by reflection mirror 9 again and is irradiated to measured object 10. The reflection light from measured object 10 is condensed by condenser mirror 11, and the light intensity is measured by Pbs cell 12. Reflection light components of respective wave length are detected and operated, thereby calculating actual water content.
