Water Quality Sensors
RYD03-PH
Digital pH Sensor
Product Overview
The RYD03-PH is a digital pH sensor with RS485 interface and standard Modbus protocol. Its industrial composite electrode with double-junction reference resists medium back-diffusion for long service life. Built-in PT1000 temperature sensor with compensation achieves Β±0.1 Β°C accuracy. Corrosion-resistant housing with IP68 protection suits harsh environments.
