How to continuously monitor the DO (dissolved oxygen) fluctuations in the plating bath?

Continuously monitor DO fluctuations in the plating solution. We will introduce methods for visualizing changes that are difficult to capture with manual measurements and how to utilize them in process management.

Are you fully aware of the fluctuations and trends in the dissolved oxygen (DO) levels during the plating bath operation? DO can change due to factors such as liquid temperature, stirring, contact with air, and reaction conditions within the bath. In processes where DO is related to reactions or precipitation states, it is important to understand not only the values at the time of measurement but also their changes. ■ Improving process management efficiency through continuous DO measurement By continuously measuring DO, you can capture changes during operation that are difficult to detect with periodic manual measurements, and accumulate data to examine the relationship with process conditions. Additionally, by utilizing alarms and signal outputs to external systems based on set values, you can create a system to monitor deviations from management ranges. One of the devices that can be used for continuous monitoring of DO in plating baths is the water quality monitoring controller "HI 520." 【Features】 ■ Modbus/RS485 compatible ■ 4-20mA analog output ■ Up to 5 relay contacts ■ Can connect 2 sensors to one main unit * For more details, please download the PDF or feel free to contact us. * The compatibility of the DO sensor and measurement conditions need to be confirmed based on the composition and temperature of the plating solution.
