Superior performance and lifetime compared to most any OEM sensor due to optimal selection of materials, design and workmanship for each built-to-order sensor. A very low total cost of ownership is possible due to superior service lifetime and extremely competitive sensor unit cost comparable to much lesser quality sensors from competitors. All sensors are made in the USA.

These conductivity sensors can operate in the most difficult of process conditions and interface with most existing instrumentation. Alternatively, complete electrochemical systems including mating transmitter can also be readily supplied as detailed in the conductivity measurement with the 3TX-CON transmitter brochure. Through our custom built-to-order design philosophy and business model, many applications that cannot be serviced by our competitors are quite feasible for our conductivity product line.

A selection of photos to represent the various types of conductivity are shown below together with various technical specification sheet for the same. These photos are not meant to exhaustive but rather only illustrative. Many additional photos, drawings and other technical details are available upon request from the factory.
