  • Conductivity of ultra pure water and low conducting solutions
    Two electrode measuring cells with concentric electrodes of stainless steel and flow vessels made of glass or stainless steel for measurements of ultra pure water

    - Precise measured values thanks to concentric electrodes without boundary fields
    - Includes flow vessels to prevent wrong results due to carbon dioxide
    - No polarization effects thanks to stainless steel electrodes
    Ultrapure water conductivity cell with built-in temperature sensor and waterproof plug, cell constant K = 0.1 cm-1, glass flow-through vessel D01/T.
    Trace conductivity cell with built-in temperature sensor, cable and waterproof plug, cell constant K = 0.01 cm-1, stainless steel flow-through vessel.
