RS485 pH, ORP and Temperature Sensor: Modbus RTU, Water Quality Monitoring, pH, ORP and Temperature

The RS485 pH, ORP and Temperature Sensor is a high-precision sensor for water treatment, smart agriculture, and environmental monitoring. It continuously measures pH, oxidation-reduction potential (ORP), and water temperature. Temperature compensation and configurable signal filtering help ensure stable readings under changing conditions. For easy integration, it supports RS485 Modbus RTU communication and 4.5–28 V DC operation. Moreover, its IP68-rated design, 3/4-inch NPT threads, and built-in electrical protection ensure reliable long-term use.
