Refillable Platinum Redox Combination Electrode

Oxidation reduction potential (ORP) otherwise known as a REDOX potential measures an aqueous system’s capacity to either release or accept electrons from chemical reactions. When a system tends to accept electrons it is an oxidizing system. Conversely, when it tends to release electrons, it is a reducing system. Like pH, it is not a measure of a concentration directly, but of an activity level....

You will find there are a lot of different models of pH meter ranging from simple pen devices to high end bench top meters and not to mention the large choice of electrodes to choose from. Here's an overview of what you need to know about pH: What is pH? pH meters measure the degree of acidity or basicity of a solution which is proportional to the amount of Hydrogen ions there are in ...

Traditional glass pH electrodes are very delicate and need regular care to keep them in good working order. If your electrode has been damaged by exposure to incompatible chemicals such as proteins, heavy metals or sulphides, you may be able to clean and revive it using specialized cleaning solutions...
