Yokogawa SC42-SP34 Plug-In Conductivity Cell Sensor CC 0.00990 cm 150C 230F Max

Description:

The Yokogawa SC42-SP34 Plug-In Conductivity Cell Sensor is used 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, along with an integrated temperature element for accurate temperature compensation. With a very low cell constant, it is optimized for high-purity water and low ionic concentration applications.

Applications:

The Yokogawa SC42-SP34 is used in industrial environments for continuous monitoring of conductivity in low-conductivity liquid processes. It is commonly deployed in power generation (boiler feedwater and condensate), semiconductor manufacturing, pharmaceutical water systems, and high-purity chemical processes. The sensor enables accurate detection of contamination and supports strict process quality control.
