The Online Digital Modbus PH Sensor developed and produced by Daruifuno is designed for real-time pH monitoring of water quality. Digital electrodes offer higher measurement accuracy, ensuring precise pH readings with real-time output. Unlike analog pH sensors, digital sensors provide direct real-time digital output without requiring additional conversion devices. This is achieved through its internal RS485 interface, which supports the Modbus communication protocol, enabling seamless integration with various equipment and systems.
The DPH790 Online Digital Modbus?pH Sensor features internal calibration data storage, allowing for plug-and-play functionality. Its latest design incorporates a PPS shell, which is resistant to high temperatures and corrosion, making it suitable for harsh environments. The sensor is highly stable and durable, with a modular structure for easy installation and use.
?
The Online Modbus pH Sensor is widely used in laboratories, scientific research, industrial process control, water treatment, environmental monitoring, agriculture, hydroponics, the food and beverage industry, swimming pools, and more. It supports continuous monitoring of drinking water, tap water, and sewage.
