High Precision Conductivity Sensor for Pure Water Applications

Pure and ultra-pure water applications demand a high precision conductivity sensor for pure water. Even trace ionic contamination can alter resistivity and compromise sensitive processes.

Why Conductivity Measurement Is Critical

In pharmaceutical, semiconductor, and power generation plants, water purity directly affects product quality and equipment life. Conductivity is the fastest way to detect ionic breakthrough in deionization beds and RO membranes.

Choosing the Right Cell Constant

• K = 0.01 cm⁻¹: Best for ultra-pure water below 1 µS/cm.
• K = 0.1 cm⁻¹: Suitable for pure water and RO permeate up to ~200 µS/cm.
• K = 1.0 cm⁻¹: Used for general process water and higher conductivity ranges.

Material and Temperature Considerations

Use platinum or graphite electrodes with PEEK or stainless steel bodies for chemical compatibility. Automatic temperature compensation to 25°C reference is essential because pure water conductivity is highly temperature-dependent.
