The pollutants emitted by humans into the oceans continue to threaten people's own safety and health, threaten the proliferation of wild animals, and erode the natural features of coastal areas around the world. UN Secretary-General Ban Ki-moon has called for individuals and groups to have an obligation to protect the marine environment and carefully manage marine resources.
For marine organisms, the dissolved oxygen content is related to the growth, extinction, and recovery of organisms, and is also a major factor affecting the shape, type, and quantity of organisms. Therefore, studying the dissolved oxygen content of seawater is an important indicator for studying marine species and living conditions.
The Ohaus engineers followed the Marine Life Research Group of Zhejiang Ocean University to the sea area of ​​Dongshan Island for sampling marine life. During the sampling process, the researchers selected the Ohaus ST20 pen measuring instrument and the st400d portable dissolved oxygen meter to test the ph value and dissolved oxygen content of the seawater at the sampling point. Researchers at the Marine Biosciences Group said that Ohaus's water quality instruments are easy to use, accurate, and ideal for outdoor operations, providing important information for their outdoor research.
