Conductivity standards

Conductivity has a wide range of applications and is used in various industries including, semiconductor manufacturing, power generation, chemical, pharmaceutical, food and beverage processing, metal and mining, textiles, pulp and paper and environmental monitoring of water quality. In most cases conductivity is an aqueous based test where it proportionally reflects the degree of water purity, the lower the conductivity of water the higher it’s purity.
