GF Signet 3-2850-51-41V Conductivity and Resistivity Sensor

GF Signet 3-2850-51-41V is an integral PVDF conductivity/resistivity sensor electronics unit with inline 3/4" NPT mounting, designed to pair with Signet conductivity electrodes for in-line process monitoring. As part of the 2850 Conductivity/Resistivity Integral Systems PVDF family, it provides a digital (S3L) output, a cell constant of 1.0, and is factory-calibrated for maximum out-of-the-box accuracy, enabling reliable measurements across compatible electrode configurations. The inline mounting and 3/4" NPT connection, combined with PVDF construction, deliver chemical resistance and straightforward installation into piping or flow cells, supporting use in water-treatment, pharmaceutical, and chemical-processing environments. It is rated for process temperatures from 14°F to 185°F, allowing stable operation in moderate-temperature streams, and is intended for use with Signet conductivity electrodes to measure conductivity and resistivity, with Signet electrodes suitable for high-purity water monitoring and other chemical applications.
