Understanding Conductivity Measurement

Basic Principles

Conductivity is measured by passing an electrical current between two electrodes immersed in the water sample. The resistance of the water is inversely proportional to its conductivity. For example, a higher concentration of dissolved ions will result in a lower resistance and higher conductivity. This is why conductivity measurement is a reliable indicator of water quality.

Applications

Conductivity meters are used in various industries:
- Pharmaceuticals: Ensure the purity of water used in manufacturing processes.
- Semiconductor Manufacturing: Monitor ultra-pure water for cleaning and rinsing processes.
- Water Treatment: Measure the effectiveness of water purification processes.
- Environmental Monitoring: Assess water quality in natural bodies of water.
