Equipped with a maintenance-friendly galvanic battery-powered sensor.
The ECO531 series is a dissolved oxygen meter equipped with a maintenance-friendly galvanic battery-operated sensor. It can directly read both dissolved oxygen in mg/l (ppm) and saturated oxygen concentration in percentage. The ECO531 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 be used in deep water areas. The 3-stage LCD display with backlight provides ease of use and wide visibility both day and night, while the energy-saving design and configurable auto power-off function ensure a long lifespan for the two AA batteries that power it. It supports maximum/minimum and hold display functions.
