Applications/Examples of results
The MC8DO-531S series can be used for water quality monitoring in various applications such as freshwater and seawater aquariums, fish farms, and wells. Simple calibration can be performed through button operation in the atmosphere, and by attaching the GSKA cap that protects the membrane, it can also be used in deep water areas. The backlit 3-level LCD display provides ease of use and wide visibility day and night, while the energy-saving design and configurable auto power-off function ensure a long battery life for the two AA batteries used as the power source. It supports maximum/minimum and hold display functions.
