Electrodes

You can have the most sophisticated pH meter in the world, but if your electrode is not operating to a high level of quality, then your readings will not be as accurate as you want. That's why we at Hanna put as much time and effort into designing and manufacturing our electrodes as we do to our meters. 

In recent years there has been considerable progess in electrode manufacturing, achieving notable high levels of accuracy. Today an electrode is an accurate, compact sensor that is easy to use. Because of its qualities and the ease with which it can be cleaned, the glass body is close to the ideal solution for measuring pH; the only problem is the fragility.

This has pushed manufacturers towards the production of electrodes with a stronger protective sheathing - a plastic cylinder. This has solved the problem of fragility at the cost of performance; plastic electrodes do not break but cannot withstand high temperatures and are even more difficult to clean. Fortunately, Hanna manufactures both types of electrode to suit a variety of applications. For decades, we have continually provided technologically innovative products for our scientific clientele throughout the world. We introduced the first electrode with enclosed temperature sensor in 1984 and the first pre-amplified electrode with AmpHel ^® connector in 1988. Hanna, backed by its many years of experience, continuously innovates in the electrode manufacturing and design field.

We offer electrodes with a range of tip shapes depending on your requirements (spherical, conical and flat, by the way) with 4 different pH sensitive glass formations and a whole range of other specifications, simply have a look in the shop to see what's right for you.
