What is Conductivity Measurement?
What is Conductivity? Conductivity is the ability of a material to pass an electric current. It is the reciprocal of resistivity. It is typically measured in aqueous solutions, and in this context, it can be defined as the ability of a solution to conduct an...Read More
Why Measure The Conductivity of Water?
Water conductivity measurement refers to testing a sample of water to see how well it can conduct an electrical current. Pure, distilled water has extremely low levels of conductivity, and so the presence of other elements can increase conductivity. For example, sea water contains a...Read More
A Guide to Reference Electrodes
The purpose of a reference electrode is to provide a constant and defined potential. This potential is determined by the electrolyte inside the electrode, and the reference element used. Most electrodes are combination electrodes, meaning they combine a stable reference and a working cell (half-cell) in one...Read More
Why are educational electrodes an important tool?
Since 1991 Sentek has been providing a range of electrochemical sensors for use in science, industry and education. Many schools and colleges will use educational electrodes as part of their practical lessons, to help educate students on measurement and analysis techniques. Measurement using pH sensors...Read More
How do ion selective electrodes work?
Ion selective electrodes allow us to measure the activity of a specific ion in a sample, by measuring the potential of a measuring cell which has a membrane that is specific to a certain ion, against the potential of a reference cell. They allow fast...Read More
Measuring dissolved oxygen in water and why it’s important.
Dissolved oxygen (DO) is a measure of how much oxygen is dissolved in water. It has important chemical and biological implications across a large range of applications that are vital for everyday life. We can study water sources to get an idea of the water...Read More
