Info

Process Unit 73 LF Simple Conductivity Measurement Fig. 9–1, page 9–3 shows how the Process Unit 73 LF is configured for simple conductivity measurement with automatic temperature detection and conductivity signal evaluation by a connected recorder. You can connect 2-electrode cells or 4-electrode cells to the Process Unit 73 LF. Cell selection depends on the measurement range: For measuring low conductivity values, you should use 2-electrode cells (e.g. Models SE 604 or ZU 0071, see page 14–12, 14–9) For measuring high conductivity values, you should use 4-electrode cells (e.g. Model SE 600, SE 602 or SE 603, see page 14–4) Especially for 2-electrode cells, the range not only depends on the cell constant but also on the electrode surface. For information on selection of suitable cell constants, refer to ISO 7887 (DIN 38 404.1), for example. 9–2 Capabilities
