pH Meter: A device used to measure the acidity or alkalinity of a solution. pH meters operate based on the principle of a primary cell, where the electromotive force (EMF) between the two electrodes of the primary cell is determined by the Nernst equation. This EMF is related not only to the properties of the electrodes themselves but also to the concentration of hydrogen ions in the solution. There is a corresponding relationship between the EMF of the primary cell and the concentration of hydrogen ions, with the negative logarithm of the hydrogen ion concentration being the pH value.
Currently, the most commonly used method for measuring water pH in industry is the potentiometric analysis: many electrodes and contacting media are highly corrosive. To better adapt to all-weather working environments, Meisu Measurement and Control has upgraded to a special electrode made of Teflon, which can better withstand strong acids and alkalis, resist corrosion, and is suitable for use in harsh environments. It is also connected to the measurement instrument (MX-PHYB-01). This effectively measures and detects the acidity and alkalinity of the water quality.
