Yokogawa SC42-SP34 Plug-In Conductivity Cell Sensor 0.01cm-1 142PSI Pt1000 302℉

Description:

The Yokogawa SC42-SP34 Plug-In Conductivity Cell Sensor is used a contacting (2-electrode) conductivity sensor designed for high-accuracy measurement of low-conductivity liquids. It features a stainless steel body with PEEK insulation and an integrated Pt1000 temperature element for precise temperature compensation. The plug-in design allows easy installation and removal, while the pre-calibrated cell constant ensures consistent and reliable measurement performance.

Applications:

The Yokogawa SC42-SP34 is used in industrial environments for continuous monitoring of conductivity in ultra-low conductivity liquid processes. It is commonly deployed in boiler feedwater systems, condensate polishing, reverse osmosis (RO), semiconductor, and pharmaceutical water systems. Conductivity measurement provides a reliable indication of ionic contamination and overall water purity.
