While it is a common belief that water is a good conductor of electricity, pure water is not. In reality, pure water that does not contain ions or other microscopic particles is actually a poor conductor of electricity. Thus, for various industries, analyzing the water composition for the possibility of conducting electricity is a crucial task. A conductivity sensor is used to analyze the number of ions in the water as well as its capacity for conduction. This equipment is often used in treating drinking water and wastewater.
