Has anyone used E+H’s online pH meters? How long do they generally last?
Thread Content
As the title suggests, I’m looking for recommendations from those who have used them – what pH meters offer good value for money.

With so many pH meters in use, Yokogawa is still the most durable choice
The electrodes need to be selected carefully; those chosen properly can last for over half a year. We’d be happy to work together if there’s a chance!
What company are you guys from? We use it for desulfurization
What electrodes are generally used for desulfurization?
Shanghai Kangchuang – we are a chlor-alkali enterprise; it’s used in Inner Mongolia. Let me know what your requirements are
In our company, the electrodes are replaced every six months, even if they’re not damaged, as it’s said to affect accuracy. We use Mettler electrodes!
Discussing the service life of a pH meter in isolation from its application conditions and environment is an inadequate understanding of such a meter. Since a pH meter is a system that measures potential based on the electricity generated by a galvanic cell composed of a pH electrode and a reference electrode, its service life depends on factors such as the electrodes, the converter or transmitter, the mounting accessories, the operating environment, and the ability for maintenance. No matter how good a pH electrode is, its lifespan will not be long if it is exposed to mechanical vibrations, friction from solid particles, or the influence of interfering components. But in some applications where the conditions are milder, it can even last for half a year or a year. The service life and performance of an online pH meter are related to its selection, installation, and maintenance.
CPF81D is suitable for desulfurization projects, used for measuring gypsum slurry; it has good electrode wear resistance!
The PH electrode is a consumable item, E+H
