Description

Product Description

pH sensors and probes are usually communicated in two ways: analog and digital. Among them, the analog signal output refers to the analog signal output of the PH Sensor converting the pH value to 0-5V or 4-20mA through the transmitter; Digital signal output refers to the pH sensor through digital communication protocols (such as RS485, Modbus, etc.) to output the pH value in the form of digital signals.

Advantages

1. High precision: The Digital pH Sensor adopts a digital measurement method, which can achieve higher accuracy and stability and improve the accuracy of measurement.
2. Multiple communication methods: digital pH sensor can exchange data with other devices through a variety of communication methods, such as RS485, Modbus, etc., to facilitate data collection and processing.
3. Automatic calibration: The Digital pH Probe can realize automatic adjustment and calibration through the automatic calibration function, reduce manual intervention, and improve the reliability of measurement.
4. Remote monitoring: realize remote monitoring through the Internet and other means, which is convenient for users to remotely control and collect data.
In short, digital pH probes have many advantages and have gradually become an important measurement tool in the field of industrial automation.
