Section 1 Product overview
The Intellical CDC401 series conductivity probes are digital electrodes that measure the electrical
conductivity, salinity, resistivity or total dissolved solids (TDS) of wastewater, drinking water and
general water samples. The probes have a graphite, 4-pole conductivity cell and a temperature
sensor. The standard probes are for laboratory use. The rugged probes are for field use. Refer to
Figure 1.
