Product Features

Easy to integrate and operate
According to the complete water quality testing system developed by power plant users. The company can provide a variety of products for users to choose from, in the hope that these products can match each other and form a flexible solution to meet your unique needs. The comprehensive approach adopted can comprehensively save your time in various aspects such as design, installation, training, maintenance, and operation.

Save design time
The same product platform means you spend less time searching for design files or specification configurations. Simultaneously enabling you to create and reuse design templates.

Easy to install
Interchangeable components, a universal user interface, and support from the same technical team can make installation faster and easier.

Simplify training
A single platform can minimize product training time and enable faster mastery of new system usage.

Simplified maintenance and operation steps
Adopting common menu guidelines reduces specificity; Provided step-by-step operational guidance for maintenance and calibration processes. When troubleshooting is required, the system will send standard visual alarms for each parameter to notify the operator. Pre installation of membrane covers and factory pre adjustment of sensors have significantly reduced start-up and maintenance time.

Working principle

The measurement of dissolved oxygen is based on the well-known Clark cell principle, where the oxygen permeable membrane isolates the water sample from the electrode, so there is no need to adjust the sample.
Other reducing or oxidizing ions do not interfere as they cannot pass through the breathable membrane.
Apply a constant voltage to both electrodes to maintain a constant potential for each electrode. The gold working electrode (cathode) will reduce dissolved oxygen to hydroxide ions:
O2 + 2H2O + 4e- --> 4OH
The oxidation reaction occurs on the surface of a large silver electrode (anode):
4Ag+ + 4Br - --> 4AgBr + 4e-
The oxidation-reduction reaction generates a diffusion current, which is proportional to the concentration of dissolved oxygen.
