Yokogawa SC42-P24 Stainless Steel Electrode Conductivity Sensor
Product Overview
The product we are introducing today is SC42-SP24. Yokogawa SC42 series contact conductivity sensor designed specifically for online conductivity measurement in industrial processes. It is used to monitor the conductivity, salinity, and water quality purity of aqueous solutions. The all stainless steel body structure has the ability to withstand pressure and corrosion, and is widely used in chemical processes, power plant water treatment, pure water preparation, sewage, pharmaceutical process water and other working conditions.
The SC42-SP24 electrode comes with a factory calibration certificate and provides factory calibration constants, which can be directly used with the Yokogawa transmitter to achieve stable and continuous online water quality analysis. The product serial numbers we provide can be traced on our official website.
Our company offers good prices for Yokogawa DCS, PLC modules, cards, electrodes, analyzers, and sensors. We look forward to your inquiry.
