| Research Abstract |
The test model of optical-fiber CRDS CO2 meter was developed, and its performance was estimated using 2000 ppm CO2 gas. In addition, the liquid-side mass balance method was developed, and its method was verified in a wind wave tank. The results showed that the temporal and spatial resolutions of the test model were 30 s and 10 mm3, respectively, and their resolutions were confirmed to be higher than commercial CO2 meters. Also, the values of the CO2 flux across air-water interface measured by the new mass balance method corresponded to those measured by previous air-side mass balance method.
