Dissolved oxygen probe

Dissolved oxygen probes measure the dissolved oxygen content in water through electrochemical or optical methods. Electrochemical probes utilize the reduction reaction of oxygen on electrodes to generate an electrical current, while optical probes are based on the quenching effect of oxygen on fluorescence at specific wavelengths. They are used to monitor oxygen levels in water bodies and are applied in environmental monitoring, aquaculture, and water treatment processes.
Selection
Select electrochemical or optical types based on the measurement environment; consider the matching requirements for range and accuracy; confirm the corrosion resistance of the probe material; check the temperature compensation function; evaluate maintenance cycles and calibration requirements; match the interface protocols of existing instruments; verify that the protection rating is suitable for the usage scenario.

Ultrasonic Thickness Gauge Selection: Technical Considerations for Probe Configuration and Measurement Modes
This article primarily introduces the technical factors to consider when selecting an ultrasonic thickness gauge. In terms of probe configuration, the frequency affects both resolution and penetration depth, while crystal size determines adaptability to curvature and surface conditions. Dual-element probes offer a smaller dead zone compared to single-element probes, and delay-line probes are suitable for thin-wall and high-temperature applications.
Coulometric thickness gauge measures the sealing quality of anodic oxide films.
This article introduces a method for assessing the sealing quality of anodic oxide films using a coulometric thickness tester. The sealing quality affects the corrosion resistance and wear resistance of the oxide film. Based on electrochemical principles, the coulometric thickness tester evaluates the sealing effectiveness by measuring the electric charge required to dissolve the oxide film, providing objective and repeatable results.
