FAQ pH measurement

In this blogarticle we answer to possible questions, that may occur to you during installation and operation of our instruments. We also respected common questions.

The benchmark for pH measurement

Today, measurement results must be comparable and reproducible everywhere and under all conditions. To meet this requirement, common conventions in metrology are used, comparable to the former original kilogram in weighing technology. Our pH buffer solutions are of course traceable to modern international standards, hence the name "Trace". The basis for this is provided by DAkkS and NIST certified secondary standards of the highest quality.

New Brochure "Sensors for Field & Lab"

In our new brochure you will find all necessary information about our WTW® electrodes and sensors, the design of a pH electrode, IDS electrodes, technical specifications, buffer solutions and a selection guide for choosing the right pH electrode.

Calibration and adjustment of a pH electrode

Why do you have to calibrate? The pH value of an aqueous solution is determined with pH measuring instruments, also known as pH meters. The accuracy of the pH measurement depends on the calibration and adjustment. The adjustment is the setting of the pH meter to the data of the pH electrode (slope and zero point) determined by calibration. Therefore, regular calibration is very useful.

Operation, care and storage of pH electrodes

Special emphasis should be placed on the maintenance and care of sensitive electrodes to optimize their service life. To extend their life, and to get the best results from your pH electrodes, we recommend following our simple advice. Remember, the electrode must always be matched to the application to obtain the best possible results.

Continuous measurement of the pH value in drinking water – using little with intelligent sensors

Low consumption with continuous measurement - the technologies from IDS and <span style="font-variant: small-caps;">IQ Sensor Net</span> make it possible. Combined with other parameters, you can reliably monitor your drinking water quality.

Continuous measurement of ORP in drinking water applications – the correct sensor handling.

Oxidation-Reduction Potential (ORP) measures the ability of water to either oxidize or reduce substances, which is crucial for assessing water quality and disinfection effectiveness. Find out how you can continuously measure ORP with Xylem’s measurement products.

Which pH electrode do I need? What is crucial when selecting a pH electrode?

For successful pH measurement, the selection of the appropriate pH electrode is very important. The pH electrode influences the measurement result. But which pH electrode is best suited for which application and guarantees an optimal result for the pH measurement?
