Pathfinder Instruments Provides Conductivity Probes & Transmitter
When It Has To Be Accurate
Our Sensors monitor a number of important measurements:
- The purity of water to be used in pharmaceutical and semiconductor processes
- The effectiveness of the filtration process for potable water
- The mineral parts-per-million in desalination systems
- The total dissolved solids for waste water treatment applications
- The purity of water in applications where electroconductivity must be avoided
When it has to be accurate, think Pathfinder Instruments!


Low-cost Pathfinder Conductivity Probes are suitable for use with most portable conductivity meters. Add a simple mounting gland fitting, and you can use these in process applications. Mount them inline, in a pipe “T” fitting, or submerge them into a tank or open channel.
Pathfinder CS-100 Conductivity Probes (K=0.1) are temperature compensated conductivity electrodes constructed of stainless steel and CPVC, used for measurements in the low ranges, from 0 to 10uS up to 0 to 750uS.
These cost-effective probes can be paired with the CT-1000 conductivity transmitter (4 – 20mA Output) or the Sensorex model TX20 conductivity controller. Standard cable length is 10 ft (custom lengths available up to 60 ft).
Pathfinder CS-100A (Stainless Steel) Conductivity Probe
The new Pathfinder CS-100A has joined our family of quality conductivity probes. Manufactured from high quality stainless steel and CPVC wetted parts, this probe features new connector fittings that allows variable insertion depth and ½” or ¾” MNPT connection.
As with all of our CS-100 probes, the new Pathfinder CS-100A can be paired with the CT-1000 conductivity transmitter. Contact us for more information.
Pathfinder CT-1000PT Conductivity Transmitter
This is a 2-wire 4-20mA output conductivity transmitter featuring encapsulated construction, high performance, and small size. DIN rail mounting hardware is available.
It works with 4-wire conductivity probes incorporating temperature compensation of the conductivity readings.
Our most popular model, the CT-1000PT-10US-K0.1 measures conductivity in the lowest range — 0 to 10uS.
