Conductivity Meter - Observing the World

How conductivity meters help us observe the world

The advancement of science is strongly dependent on our ability to observe the world. Werner von Siemens developed the idea of electrical conductivity of solutions based on Michael Faraday’s work. Siemens also invented telegraph, the first electric railway, and the first electrical elevator, so he was quite good at taking an understanding of science and creating useful things.

Overall conductivity of a solution is a relatively simple measurement to make, but it can provide important insight into what is present in a solution. It has other advantages, particularly that it can be performed rapidly, so conductivity is an appropriate measure for routine testing of solutions and for observations that need to be made, peridically, over long time spans.

Conductivity measurements inform scientists about a number of natural and human engineered systems. These include:

The conductivity meter changed the way we can investigate nature by making it possible to have accuate, quantitative measures of concentrations of ionic substances in aqueous solution. This value is important in understanding many key aspects of such soliutions. Living on a water planet, this ability is very important.
