Custom Probe LengthsClark Reliance now offers a full selection of conductivity probes to meet your specifications. In 1959, we developed and introduced the conductivity probe technology to the industry, for boiler drum level applications. Now, we have added brazed and compression-type probes as options for our conductivity probe level instrumentation systems, which include Water Columns, Electro Eye-Hyes, Turbine Water Induction Protection systems, and Levalarms. With the most extensive field experience and knowledge in this business, Clark-Reliance now offers a complete selection of brazed conductivity probes.

Probe Repairability. System economy is enhanced by the availability of off the shelf Probe Repair Kits.  Replaceable parts include gaskets and other components that are susceptible to routine wear factors over extended periods of time.  (Available for ZG and FG probes).

Our line of brazed probes offer one piece construction with high reliability for harsh applications or boilers that cycle frequently. These probes are manufactured to the highest quality standards.  Each probe is tested with 3 separate methods, to ensure reliability for a wide range of boiler applications, with variable water chemistry.
