Collection: PH & Conductivity Meters

pH meters are instruments used to measure the pH or the hydrogen-ion activity in water-based solutions. They measure the difference in electrical potential between a pH electrode and a reference electrode, hence indicating the acidity or alkalinity of a solution. Hence these are also called potentiometric pH meters, as they measure the voltage between the two electrodes and display the result converted into the corresponding pH value. Conductivity meters are used to measure the salt concentration, conductivity of a solution.pH meter, conductivity meter, as well as in combination, is available from various brands on
