Electrodes can be freely attached and detached or exchanged. In addition to pH, water temperature and Redox/ORP (oxidation-reduction potential) can also be measured.
The ECO51x series is a waterproof compact pH meter that can be used in various applications such as water quality monitoring in aquaculture, plant cultivation, and agricultural purposes. The ECO511 can achieve high-precision temperature compensation by connecting a Pt1000 temperature probe, and it is also capable of measuring Redox/ORP (oxidation-reduction potential) by connecting a dedicated electrode. The backlit 3-stage LCD display provides ease of use and wide visibility day and night, while the energy-saving design and configurable auto power-off function ensure long battery life. Regular calibration with buffer solutions GPH-DOS-4/7/10 allows for accurate measurements over an extended period.
