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?

pH measurement shows a wide range of applications, from routine measurement in aqueous solutions up to special applications in a variety of media such as strong acid or alkaline solutions, with suspended solids or non-aqueous phases. The sample consistency can vary from liquid to firm, and measurements can be taken in a sheltered laboratory environment or outdoors in harsh conditions. Across all these variables, the range of SenTix® electrodes has a solution.

The SenTix range of electrodes includes low-maintenance electrodes, precision electrodes, electrodes with or without temperature sensors, analogue electrodes and digital electrodes including IDS technology.
