RYD03-EC
Digital Conductivity Sensor
Product Overview
The RYD03-EC is a digital conductivity/salinity sensor with RS485 interface and standard Modbus protocol. Industrial four-electrode titanium construction covers the full conductivity range with automatic 10Γ range switching. Stable cell constant, automatic surface contact resistance compensation, and an easy-clean flat measuring face. Salinity and TDS outputs are also available.
