A PH Meter is an instrument used to measure the acidity or alkalinity of a solution. The information provided by this equipment expresses the degree of acidity of an acid or base in terms of the activity of hydrogen ions.
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 the pH can be obtained using indicators or pH ribbons, which change color as a function of the variation of the pH level, but these indicators present limitations in terms of accuracy and can be difficult to interpret correctly in dark or colorful samples, and this error can be largely corrected through the use of pH meter.
• Economical online PH Controller comes with an industrial pH electrode.
• 1 to 3 points calibration with auto-buffer recognition.
• Selectable pH buffer group, including the USA and NIST options.
• Automatic temperature compensation ensures accurate readings over the entire range.
• Automatic electrode diagnosis helps the user decide whether to replace the sensor.
• Setup menu allows setting the pH buffer group, number of calibration points, alarm limits,
hysteresis value, 4 to 20mA output, etc.
• Reset function automatically resumes all settings back to the factory defaults.
A PH Meter works through an electrochemical cell mechanism, where the H + in the chemical reaction allow determining the concentration of them in solution. When determining pH with a pH meter, a reference electrode and a measurement electrode are used, which are sensitive to analytes.
In other words, a PH Meter is a high impedance amplifier that accurately measures the minimum electrode voltages and displays the results directly in pH units on an analog or digital display. In some cases, the voltages can also be interpreted for special applications or use with ion selective or oxidation / reduction potential electrodes.
