SE604 2-Electrode Conductivity Sensor

Ex-certified digital 2-electrode conductivity sensor with Memosens technology for ultrapure water down to 500 µS/cm.

The SE604X-MS is a rugged 2-electrode conductivity sensor built for accurate measurement of low and very low conductivity levels, ideal for ultrapure water applications such as boiler feed water and condenser monitoring. Its coaxial stainless steel electrode design ensures stable readings regardless of installation orientation, while Memosens digital technology delivers galvanic isolation, integrated diagnostics, and reliable signal transmission. An integrated NTC temperature detector supports precise compensation, and the detachable outer electrode simplifies cleaning and maintenance. Approved for use in hazardous areas, it suits demanding power plant and process water monitoring tasks.
