Ph meters

A pH meter is a laboratory instrument for scientific use, which measures the activity of the hydrogen ion in aqueous solutions, indicating its degree of acidity or alkalinity expressed as pH, is used in laboratories and in multiple other fields or areas; a pH measurement can be obtained using pH indicators or tapes, or meters such as pH meters, portable meters or pH electrodes.

This pH meter instrument makes a measurement of the pH by a potentiometric method, based on the fact that between two solutions with different H + a potential difference is established, which determines when the two solutions come into contact a flow of electric current occurs, in practice the pH measurement is relative, since the pH of a sample is compared with that of a known pH standard solution.

Types of pH meters a Laboratory may need

Portable

Portable pH/ion meter: calibration from 2 to 5 points, selectable ion concentration units and is required to measure pH, mV and ion concentration, accuracy 0.5% FS. (there are a variety of models).

You should keep in mind that the most accurate measurements are obtained using a pHmeter. The measurement system is made up of three parts: a pH measurement electrode, a reference electrode and a high input impedance meter. The pH electrode can be considered as if it were a battery, with a voltage that varies according to the pH of the measured solution. The electrode that measures pH is a glass bulb sensitive to hydrogen ions, with an output in millivolts that varies according to changes 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 the hydrogen ions.

Table pH meters

Desktop pH meter: it is equipped with a 7-inch TFT screen, 1 to 5 point calibration with automatic recognition for USA, NIST and DIN buffers; temperature coefficient of the solution compensates for pure water samples and refers to the pH at 25° C. (variety of models).

The calibration is carried out with at least two standard buffer solutions that cover the range of pH values ​​to be measured. For general purposes, buffers at pH 4.00 and pH 10.00 are suitable. The pH meter has a calibration control to set the meter reading equal to the value of the first standard buffer and a second control that is used to adjust the meter reading to the value of the second buffer. A third control allows to adjust the temperature. More precise measurements sometimes require calibration at three different pH values.

PH Meters in Operation

The pH is the unit of measurement that describes the degree of acidity or alkalinity and is measured on a scale ranging from 0 to 14. An approximate indication of pH can be obtained using pH indicators or tapes, which change color depending on the variation of the pH level. But these indicators have limitations in terms of accuracy and can be difficult to interpret correctly in dark or colorful samples.

A pH meter is an instrument used to measure the acidity or alkalinity of a solution. The quantitative information given by the pH value expresses the degree of acidity of an acid or a base in terms of the activity of the hydrogen ions.
