Pure water conductivity measuring cells

Conventional pure water conductivity measuring cells
WTW sensors pure water conductivity measuring cell LR 325/01
WTW sensors pure water conductivity measuring cell LR 325/001
WTW sensors pure water conductivity measuring cell LR01 V

Two electrode measuring cells with concentric electrodes of stainless steel and flow vessels made of glass or stainless steel for measurements in pure water

  • Precise measured values thanks to concentric electrodes without edge fields
  • Includes flow vessels to prevent wrong results due to by carbon dioxide
  • No polarization effects thanks to stainless steel design

Pure water measurement means basically the intrinsic conductivity of purified water in the pharmaceutical industry and the production of semiconductors. This is where the LR 325/01 and the LR 325/001 come in. Both have flow vessels to prevent carbon dioxide from the air entering during the measurement process. The LR 01/V is the same as the LR 325/01 and can be connected to the Vario Cond. The LR 325/001 is capable of measuring into ranges of 0.001 µS/cm when using the suitable WTW conducitivity meters.
