Fish swimming ability measuring chamber for observing fish physiology, energy consumption, behavior, biomechanics and kinematics. Unique product design, compact enough movement space for the fish, small footprint, measurement of oxygen consumption can also be achieved. Overall made of plexiglass, you can observe the fish from above and from the side. All other parts are made of non-corrosive materials (PVC, stainless steel). The swimming tunnel is no pressure, the lid can be opened and closed, loading and unloading subjects during operation. The system is also equipped with a motor, a warm water bath and heat sink, you can achieve accurate and fast water temperature control. Features: anti-corrosion materials, simple maintenance tool free assembly, easy cleaning and transport double cover, facilitate the processing of animal adjustable blade control the flow rate of the test area speed control, analog input and output reusable wooden box, easy to transport solution oxygen and temperature probe socket: study fish swimming ability, as well as the physiological and environmental indicators measuring.
