High-frequency continuous measurements of the partial pressure of CO2 (pCO2) are crucial for constraining the spatiotemporal dynamics of CO2 emissions from inland water systems. However. direct measurements of pCO2 are scarce. and no systematic comparisons have been conducted on the suitability of the widely used measurement systems for continuous underway or long-term deployment in v... https://vacuumdoctores.shop/product-category/nozzle-part/
