SI-50 SI Marine 0-50PSU 20bar G1/2 Salinity Meter Electrode

Description

SI Marine SI-50 0 to 50 PSU 20 bar G 1/2″ Thread 316L Stainless Steel is a high-precision salinity electrode. The sensor body is constructed from corrosion-resistant 316L stainless steel and features an integrated Pt 100 resistance thermometer for real-time temperature compensation. It utilizes a four-electrode measurement principle to ensure stability and accuracy in high-conductivity marine environments. The unit is designed for continuous immersion with an IP 68 protection rating and a robust 4-pin electrical interface.
