Laboratory meters

There are multiple meters to use in laboratories, which is why you must first determine what objective you want the instrument to meet, since each one measures or indicates a different grade or volume. For example, we have turbidimeters, pH meters, ion meters, oxygen meters and conductivity meters, instruments that all are responsible for giving the most precise levels in water, air or solid substances.
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 hydrogen ions. You should be aware that the most accurate measurements are obtained using a pH meter. The measurement system consists of three parts: a pH measurement electrode, a reference electrode, and a high input impedance meter. The pH electrode can be thought of as a battery, with a voltage that varies according to the pH of the measured solution. The electrode that measures pH is a hydrogen ion sensitive glass bulb, with a millivolt output 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.

Turbidimeters: their measuring ranges

A turbidimeter is a piece of equipment used to measure the turbidity of a liquid. These devices can also set the size and concentration of suspended particles through light scattering in a tube.

These devices measure turbidity - that is, how cloudy a fluid is. What the turbidimeter does is develop an optical analysis that allows you to measure the suspended particles in a dissolved gas or in a liquid.

For this, it uses a light source and a light detector (a photocell) that is fixed at a right angle to the original beam.

The photocell, also called photoresistor or photoresistor, is an electronic part that, when it detects an increase in light, registers a change in its resistance.

The pH meter vs. Dissolved oxygen meter

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.

How does a pH meter work? You should keep in mind that more accurate measurements are obtained using a pH meter. 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.

How does turbidity work?

Turbidity; It is one of the parameters that define the degree to which water loses its quality of transparency as a consequence of the suspended solid particles found in it. The higher the concentration of particles in the water, the higher the level of turbidity.

Turbidity is calibrated with laboratory materials such as turbidimeters that determine the amount of suspended solids. Turbidimeters; They are most useful in wastewater treatment operations for its purification and subsequent supply to urban centers, as well as to artificially recharge the aquifers.

Once the turbidity level of the water has been measured, it is studied which treatment is the most suitable to meet the minimum quality levels required for the water.

Considerations for the Care and Calibration of your pH meter

A pH meter or pH meter is a scientific instrument that measures the activity of the hydrogen ion in aqueous solutions, indicating its degree of acidity or alkalinity expressed as pH. The pH meter measures the difference in electrical potential between a pH electrode and a reference electrode. This difference in electrical potential is related to the acidity or pH of the solution. The pH meter is used in many applications ranging from laboratory experimentation to quality control.
