The Pure Water Conductivity probe is used for the testing of ultra-pure water and low conducting solutions. The two electrode measuring cells are concentric electrodes of stainless-steel and flow vessels which are made of glass or stainless-steel for the measurement of ultra-water. It has a built-in temperature sensor and waterproof plug.

This probe can be used with a variety of meters including: Cond 315i, LF 320/323/325, LF 330/340A, Cond 330i/340i, inoLab Cond pH/Cond and Multi, LFF 538, MultiLab 540, Multi 350i, LF 197, LF 597 and the Cond 197i.

Key Features:

• Precise measured values due to concentric electrodes without boundary fields
• Includes flow vessels to prevent wrong results because of carbon dioxide
• Stainless-steel electrodes mean there is no polarization effects
