A new design of equilibrator for carbon dioxide monitoring in natural waters is described. It consists in a vertical tube filled with marbles through which water is flowing while equilibrating with a closed air circuit. It offers several advantages compared with classical equilibrators, among which is a fast response time (half-life constant approximately 30 s) and the potential to work in very turbid water. The proposed equilibrator is of particular interest to monitor carbon dioxide in coastal ecosystems, such as estuaries, which are known to be turbid and highly dynamic. Two performance tests and some field results are presented to illustrate the efficiency of the proposed system.
本文描述了一种用于天然水体中二氧化碳监测的新型平衡器设计。它由一根垂直的装有大理石的管子组成，水在其中流动，同时与一个封闭的空气回路达到平衡。与传统的平衡器相比，它具有几个优点，其中包括快速响应时间（半衰期常数约为30秒）以及在非常浑浊的水中工作的潜力。所提出的平衡器对于监测沿海生态系统（如河口，已知河口浑浊且动态性高）中的二氧化碳特别有意义。给出了两项性能测试和一些现场结果，以说明所提出系统的效率。
