APPARATUS FOR MEASURING POLLUTION LEVEL OF ATMOSPHERE GAS

摘要

PURPOSE: An apparatus is provided to achieve improved quality of annealed product by controlling the heating time and amount of gas in the annealing furnace through the accurate measurement of pollution level of atmosphere gas in the furnace. CONSTITUTION: An apparatus comprises a cylindrical housing constituted by a rotatable disk(308) having a plurality of through holes formed at a predetermined interval, and fixed plates(310) having a plurality of through holes, and which are disposed at the left and right side surfaces of the disk; a paper mounting unit having plural sheets of paper accommodated in the paper mounting unit, and which is mounted in the through hole formed at one of the fixed plates; and a pollution level measuring unit for measuring the pollution level of the atmosphere gas from the paper which is polluted by being exposed to the atmosphere gas discharged along an atmosphere gas discharge path.
