871CC and 871CR Series Contacting Conductivity and Resistivity Sensors

When coupled with Foxboro 875CR Series Analyzers, or 876CR Intelligent Transmitter, measure conductivity or resistivity of process solutions.

Application flexibility is enhanced by the choice of insulator materials and mounting hardware. Installations are simplified with the sliding bore piece design. The design also permits mounting hardware interchangeability and lower sensor replacement costs.

Key Benefits
