The conductivity sensor uses a two graphite plate sensing element and is automatically temperature compensated.

The Conductivity Probe is great for environmental testing for total dissolved solids (TDS), conductivity, or salinity in water samples.

The Conductivity Probe can monitor concentration or conductivity at three different sensitivity settings.

The probe has a fast response time, reaching 98% of full value in less than 5 seconds. You can load saved calibrations using the LabNavigator. Alternatively, you can do a quick two-point calibration: the probe is left out of solution for one calibration point (0 µS/cm) and is placed in a known standard (1000 µS/cm solution is provided) for a second calibration point. More precise calibration in two different standards is also possible using our software.

The Conductivity Probe uses alternating current at its electrodes; this prevents polarization and electrolysis, so that solutions being tested are not fouled. Corrosion of metal electrodes is not a problem with this epoxy-body graphite electrode. It has built-in temperature compensation, which allows you to do your calibrations in the lab, and then make measurements outdoors without temperature changes affecting conductivity readings.
