A pH meter is one of the most used equipment in a laboratory. It is used to measure the acidity or alkalinity of a solution and the information it provides expresses the degree of acidity of an acid or base in terms of the activity of hydrogen ions, so through the use of this equipment we can know the type of substance we are analyzing, as well as the type of treatment that should be given to it.
The pH meter is commonly constituted by an amplifier and two electrodes, a pH measuring electrode and a reference electrode. The reference electrode has a known, constant and stable potential. The pH-measuring electrode is a hydrogen ion sensitive glass bulb, with a millivolt output that varies according to alterations in the relative concentration of hydrogen ions inside and outside the bulb. The output of the reference electrode does not change with the activity of hydrogen ions.
The pHmeter in the lab
A pHmeter is an instrument that should not be missing in a laboratory. An inaccurate result in any of the measures of pH of the substances used in the various processes of the laboratory, can result in the total or partial loss of your results, that is why it is so important that every laboratory has the best pH meter.
The pHmeter responds to the need in laboratories to have an instrument capable of measuring pH with high precision.
