Conductivity

Conductivity sensors are measuring devices that measure the ability of a measuring medium to conduct electric current between two electrodes. The current flows by ion transport. This means that measuring media with a higher number of ions conduct the current…  Read more

Conductivity sensors are measuring devices that measure the ability of a measuring medium to conduct electric current between two electrodes. The current flows by ion transport. This means that measuring media with a higher number of ions conduct the current better.
A conductivity detector is used for digital measurements of conductivity in pure or process water.
