This machine is used in the special setting of water source treatment in the hydraulic experiment of geosynthetics, or connected with other geosynthetics equipment through a hose, which can effectively remove the gas in the water, including oxygen, carbon dioxide, etc., and provide the necessary desorption for testing. Gas water. It also provides the constant water temperature required for the experiment, which is used as a constant temperature source to provide a field source with controlled heating and cooling, uniform and constant temperature for users when working, and conduct constant temperature experiments or tests on test samples or products produced.
