Yokogawa Electric Corporation SC42-SP34 Conductivity Sensor

The Yokogawa SC42-SP34 Plug-In Conductivity Cell Sensor is a contacting (2-electrode) conductivity sensor designed for precise measurement of low-conductivity liquids. It features a plug-in design for easy installation and maintenance, an integrated temperature element for accurate temperature compensation, and a very low cell constant of 0.00990 cm^-1 optimized for high-purity water and low ionic concentration applications. Used in industrial environments for continuous monitoring of conductivity in low-conductivity liquid processes, it finds application in power generation (boiler feedwater and condensate), semiconductor manufacturing, pharmaceutical water systems, and high-purity chemical processes, helping detect contamination and support strict process quality control.
