Device: High Sensitivity Oxygen Sensor

Device: High Sensitivity Oxygen Sensor

It is a zirconia-type oxygen sensor using oxygen-conducting ceramic (YSZ).

This device is a zirconia-type oxygen sensor using oxygen-conducting ceramic (YSZ). When gas with different oxygen partial pressures flows on both sides of a yttria-stabilized zirconia tube, which has platinum electrodes baked onto both the inner and outer surfaces, an electromotive force is generated that is proportional to the logarithm of the oxygen partial pressure ratio, according to the Nernst equation. It has a fast response speed and can measure with high accuracy.

Process Fluorescent Dissolved Oxygen Sensor (Water Quality Meter) RDO Pro-X

Process Fluorescent Dissolved Oxygen Sensor (Water Quality Meter) RDO Pro-X

Low maintenance, high stability and responsiveness, corrosion-resistant fluorescent dissolved oxygen sensor (manufactured by In-Situ, USA)

This is a simple and low-cost dissolved oxygen sensor that is ideal for applications such as industrial wastewater, aeration tanks, raw water management for food and beverage manufacturing, and fisheries research and aquaculture. While the conventional model RDO PRO required a sensor cap replacement once a year, the RDO Pro-X has eliminated that regularity, resulting in lower maintenance (however, since the sensor cap is a consumable, replacement is still necessary).

[Information] A discussion on Dissolved Oxygen (DO)

[Information] A discussion on Dissolved Oxygen (DO)

In addition to manual analysis, there are methods for quantifying dissolved oxygen that utilize membrane electrode techniques and optical sensor methods.

Dissolved oxygen refers to the amount of oxygen (mg/L) that is dissolved in water. The amount that dissolves in water increases with lower water temperatures and higher pressures. Under conditions of 1 atmosphere and 25°C, it is estimated that about 8 mg/L (saturated dissolved oxygen amount) of oxygen can dissolve. This document provides detailed information about dissolved oxygen sensors, non-aqueous solvent electrodes, and other information related to dissolved oxygen. Please take a moment to read it. [Contents] ■ About dissolved oxygen ■ Dissolved oxygen sensors ・ Membrane electrode method ・ Optical sensor method ■ For BOD measurement ■ Non-aqueous solvent electrodes *For more details, please refer to the PDF document or feel free to contact us.
