Using Results and Comparison of CO2 Gas Analysis Meters in View of User

概要

CO2 Gas meter (0-20%) is usually used under the Hot Wire System, but now we are using CO2 gas meters manufactured by Leeds & Northrup Company and sound-typed gas meters, both of which are high-dense meters. The characteristic of the saturated CO2 gas recorder is the micro-max mechanism, in which the measuring cell is connected to one arm of a wheatstone bridge circuit, the reference cell is connected to an adjacent arm of it as indicated in Fig 7, and the balance of it is measured by the potentiometer circuit of the recorder. The characteristic of the sound-typed gas analysis meter is to be attributed by Microphon and Speaker, and for the density of CO2 gas to be measured by change of oscillating frequency. Until today, it has been improved so often and now is being operated very smoothly. We describe our using results and comparison of CO2 gas analysis meters in view of user as follows.
