Which pH meter/electrode do I need?...

Making sure you have the right electrode and meter for your application can be confusing, not to mention correct maintenance and what to do if you are having issues. You can find links to our support guides below to help you through the process.

If you are after an electrode selector guide for some of our most popular electrodes and what applications they are recommended for you can find that below.

Electrode Selector Guide


An introduction to pH pH, put simply is a measure of how acidic or basic a solution is. It is a measure of H⁺ions present. pH can be measured in a number of ways including test strips, indicator solution or with a pH meter and electrode. If you want to read more about the pH and the pros and cons of these methods, you can check out our introduction guide here.	How to take a pH reading and care for your electrode pH electrodes require the correct storage and regular calibration. If you have a pH meter or are looking to purchase and need to find out more about the care and maintenance process then you can read our guide here. We also include a troubleshoot sections with the most reported issues and possible solutions.	Selecting the right electrode and meter for your application So you have decided you need to purchase a pH meter with electrode, but with such a wide selection out there, how do you know which is right for you? You can read our guide on the differences between electrodes and what applications different features are good for. We also have an electrode selection guide for some of our most popular electrodes.
