DIFFUSE DENSITY TESTING DEVICE AND OPERATION METHOD OF DIFFUSE DENSITY TESTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a diffuse density testing device capable of accurately measuring the density of different kinds of tracer gases by one time of processing.;SOLUTION: The diffuse density testing device includes: a plurality of test tubes for storing an absorbing solution for absorbing a first tracer gas; a plurality of hollow pipes connected to each of the plurality of test tubes; an absorption mechanism for absorbing a gas within an air duct into each of the hollow pipes via each of the testing tubes; a second gas measurement mechanism connected to the plurality of hollow pipes and measuring the density of the second tracer gas in the gas absorbed into each of the hollow pipes; and a first switching mechanism for switching a connection destination of each of the hollow pipes between each of testing tubes and the second gas measurement mechanism.;COPYRIGHT: (C)2014,JPO&INPIT
