Description

Technical field [0001] The invention belongs to the technical field of water quality monitoring, and relates to a deep aquifer multi-parameter in-situ monitoring instrument and a method thereof. Background technique [0002] In the monitoring of groundwater or deep ocean waters, obtaining water quality information under the original temperature, pressure, and pH of the monitored water is of great significance for mastering water quality, studying chemical reaction mechanisms, and developing predictions and early warnings. At present, water body monitoring is mainly done by sampling monitoring. However, water monitoring by sampling is an offline test. The pressure and temperature environment of the tested water will change. At the same time, there is a risk of secondary pollution in the water sample acquisition process, which greatly weakens the authenticity of the measured information. Summary of the invention [0003] The present invention proposes a multi-parameter in-situ moni...
