Yokogawa SC42-SP34 Plug-In Conductivity Cell Sensor

The Yokogawa SC42-SP34 Plug-In Conductivity Cell Sensor is a contacting (2-electrode) Conductivity Cell Sensor designed for high-accuracy measurement of low-conductivity liquids. It features a 316L stainless steel body with PEEK insulation and an integrated Pt1000 temperature element for precise temperature compensation, ensuring consistent readings from ambient up to 150 °C (302 °F max). The plug-in design enables quick installation and removal in flow cells or inline process lines, while the pre-calibrated cell constant of 0.01 cm⁻¹ supports reliable measurement without on-site re-calibration. Applications in boiler feedwater, condensate polishing, RO, semiconductor, and pharmaceutical water systems reflect its role in monitoring ionic contamination and overall water purity.
