PH7 ：Smart pH Sensor

A pH meter measures the acidity or alkalinity of a solution. Acidic solutions have positively charged hydrogen ions, and alkaline solutions have negatively charged hydroxide ions. pH stands for the power of hydrogen, and it is calculated based on the number of hydrogen ions in a liquid. Because these hydrogen ions create a positive charge, an acidic solution with many hydrogen ions can easily conduct an electric current. pH meters measure that ability.
The working principle behind pH meters is potentiometry. This is the measurement of a solution’s electric potential (voltage). Remember how acidic solutions can efficiently conduct an electric current because of the positive hydrogen ions? The ability of a solution to conduct a current is called electric potential. Electric potential is key in understanding pH meter principles and applications.
A pH meter measures electric potential using 2 electrodes inserted into the liquid to create an electrical circuit. One of these electrodes, called the reference electrode, will contain a substance with a known electric potential. The other electrode, known as the sensor electrode, will be inserted into the solution being tested. The electric potential is the difference that results from comparing the reference electrode to the sensor electrode.

Delta-Phase incorporates B5014 cartridge electrode from a leading ISE supplier into standard PH7 Field Rebuildable sensors that widely covers pH measurements including most municipal water and wastewater, surface water and industrial process water and wastewater.
The PH7 sensors are good for both handheld and in situ applications and offer quick time response, minimal flow dependence and low power consumption.

The cartridge electrode features a “long life” reference element eliminating the need to frequently replace the electrode cartridge. By using PE7XXX series electrodes, optional disposable sensors are designed for special applications like High temperature, Desulfurization and High pure water etc. Both rebuildable and disposable sensors come with different mounting types such as immersion, flow-cell and insertion / retractive ball-valve assembly installations.
