Pathfinder Instruments Provides Conductivity & Resistivity Sensors
When It Has To Be Accurate
Our Sensors monitor a number of important measurements: 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. The purity of water to be used in pharmaceutical and semiconductor processes. When it has to be accurate, think Pathfinder.
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-1000 Conductivity Probes (K=1.0) are
temperature compensated conductivity electrodes, and constructed of high density, flat surface graphite, PVC, & epoxy used for medium conductivity ranges from 0 to 1000uS up to 0 to 2000uS in combination with the CT-1000 conductivity transmitter, the Sensorex TX20 controller or other brands of controllers and transmitters. Standard cable length is 10 ft, and custom lengths are available up to 60 ft.
Pathfinder CS-3000 Conductivity Probes (K=5.0) Conductivity Probes are temperature-compensated conductivity electrodes, with high-density, flat surface graphite construction similar to the CS-1000 model, but suited for high range measurements, from 0 to 30,000uS up to 0 to 135,000uS. Standard cable length is 10 ft, and custom lengths are available up to 60 ft.
Pathfinder CS-5000 Conductivity Probes (K=2.5)
Features two graphite contacts mounted in CPVC housing for a rugged, dependable sensor design. Low cost, Flat surface 3/4″ PVC/Polypro Probe with ATC, these probes measure ranges from 0 to 5000uS up to 0 to 20,000uS. Standard cable length is 10 ft, and custom lengths are available up to 60 ft.
Pathfinder CT-1000PT Conductivity Transmitter is a 2-wire 4-20mA output conductivity transmitter featuring encapsulated construction, high performance, and small size. Our most popular model! The CT-1000PT-10US-K0.1 measures conductivity in the lowest range — 0 to 10uS.
Pathfinder RC-20 Resistivity Probe (K-.007) is a Resistivity/Conductivity Probe that has an Integral Temperature Sensor for automatic temperature compensation. It comes in a variety of cable lengths. Standard cable length is 10 ft, and custom lengths are available up to 60 ft.
The Model HPT-12 transmitter converts the resistivity cell signal to a usable 1-1.2 VDC output proportional to the Megohm/cm level using an RC-20 probe.
