Guanlong pH Sensor: Industrial-Grade Precision for Continuous Water Quality Monitoring
What Is a pH Sensor?
A pH sensor is a precise measuring tool which helps the user to determine the acidity or alkalinity of an aqueous solution. It measures the amount of hydrogen ions in relation to hydroxide in the solution, providing a pH reading between 0 and 14:
pH < 7 → Acidic
pH = 7 → Neutral
pH > 7 → Alkaline (Basic)
How Guanlong pH Sensor Works
Most industrial pH sensors consist of two key components:
Measuring Electrode
It is made from special pH-sensitive glass and responds to hydrogen ion activity by producing a gel layer that interacts with the solution.
Reference Electrode
Provides a stable voltage baseline for comparison.
Submerged, the sensor measures the voltage differential between these electrodes and translates it into a readable pH reading. More sophisticated models incorporate temperature compensation to better maintain accuracy across different thermal environments.
