DIGITAL PH METER (PID) 3 POINT CALIBRATION
pH Meter is an instrument that
measures the hydrogen-ion activity in water based solutions indicating its acidity or
alkalinity expressed as pH .The device measures the difference in electric potential between a pH electrode and a reference electrode. This
difference in potential relates to acidity or pH of the solution. pH Meter is an instrument that measures the hydrogen-ion activity in water based solutions indicating its acidity or
