PASPORT Conductivity Sensor - PS-2116A

Move to Wireless!

Recommended Alternative — The Wireless Conductivity Sensor can perform most* of the functions of the PASPORT Conductivity Sensor at a lower price. Best of all, it connects directly** to your computers, tablets, smartphones and Chromebooks without the need for an interface and with no cables to get in the way.

*The Range is lower: 0-20,000 us/cm vs. 0-100,000 us/cm and accuracy is ± 10% of reading vs ± 2% of scale.

**Devices without native Bluetooth® Smart connectivity will require a low cost USB adapter - see the product page for details.



Most Conductivity Sensors use graphite probes, but our Conductivity Sensor uses platinum for greater range and improved accuracy at high and low concentrations.The result is better measurements that lead to better labs. Three ranges, push-button selectable on the sensor, allow it to be used for a wider variety of experiments without requiring recalibration.

  • Electrode houses rugged, research-grade conductors that provide superior accuracy over the entire range.
  • 0-100,000 µS/cm ranges allows conductivity measurement in order to calculate salinity from "fresh" water to sea water.
  • Replaceable probe reduces maintenance costs.

Typical Applications

  • Accurately compare conductivity of different water samples
  • Study the effects of chemical flocculants on conductivity
  • Conduct environmental studies
  • Investigate drinking water purity
