This work is related to the technical field of natural water sampling and testing, especially a liquid degassing sampling testing device, which can be used to separate the gas in the sampling liquid of seawater or fresh water, and then accurately test the dissolved oxygen and other values.

Today's oceans, rivers, and lakes require some testing to obtain useful information, including the amount of dissolved oxygen in the water. Dissolved oxygen refers to the concentration of oxygen dissolved in water. In the practice of natural water quality management, dissolved oxygen is regarded as the main indicator for judging the quality of water quality. The higher the concentration, the better the water quality. The influence of water temperature and dissolved substances in water, the higher the water temperature, the lower the saturated dissolved oxygen (concentration).

In order to know the amount of dissolved oxygen in the water body, the conventional technology uses a liquid pump to extract the sampling liquid in the water body, and then uses an optical detector or other instruments to detect the sampling liquid. However, there is often air in the liquid pump or pipeline in the sampling liquid, so that there is gas (air) accidentally mixed into the sampling liquid by external force during the sampling process, which will affect the correctness of the detection. For this reason, how to separate the gas (bubble) mixed in the sampling liquid and improve the detection accuracy is the subject to be overcome by the creation of the liquid degassing sampling inspection device.

The main purpose of this creation is to provide a liquid degassing sampling inspection device, which separates the gas (bubble) in the liquid through the centrifugal force circulation principle of the sampling liquid, and then uses it to detect the sampling liquid, thereby achieving the purpose of improving the detection accuracy.
