We have published a wealth of information on electrical conductivity, including temperature characteristics of solutions and measurement methods!

Electrical conductivity is defined as "the reciprocal of the electrical resistance measured in a container filled with an electrolyte solution, where two flat electrodes with an area of 1 m² are facing each other at a distance of 1 m." In other words, it indicates how easily electricity can flow, which can also be described as the sum of the ions contained in the solution. This document provides detailed information on electrical conductivity, including its units, temperature characteristics of solutions, and measurement methods. We invite you to read it. 【Contents (excerpt)】 ■ Measurement of electrical conductivity ■ Electrical conductivity cell ■ Cell constant ■ Display of electrical conductivity at 25°C ■ Units of electrical conductivity *For more details, please refer to the PDF document or feel free to contact us.

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.
