 pH Measurement Explained
 
At the core of water quality analysis from chemical processing and laboratory research lies a small but sophisticated piece of technology: the pH probe. While it may look like a simple glass rod, it is actually a highly sensitive electrochemical sensor designed to measure the activity of hydrogen ions. Operating on the principle of potentiometry when submerged in a solution, calculating the potential difference between the glass & reference electrodes providing precise pH measurements.
 
Dependent on the intended application electrodes are manufactured in various shaft materials: - Glass Electrodes - Polycarbonate Electrodes - Epoxy Electrodes
