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....
Quite simply, dissolved oxygen (DO) is free (non-compound) oxygen present in water. Oxygen dissolves by diffusion from the surrounding air, gained by aeration from turbid water or a waste product of photosynthesis. DO is vital to maintain aquatic life from fish to plants to bacteria and thus an important parameter to be able to measure. There are many factors to take into account when ch...
The TRUEscience team have had years of experience in supporting users of traditional pH meters. During this time they saw all the frustrations that people have when using these meters - unclear buttons, difficult interfaces, trouble saving and retrieving results. They wanted to create a new and unique way of measuring pH that makes the test quick and simple while still retaining a high level...
One of the key user frustrations the TRUEscience team came across whilst developing the TRUEscience pH meter was how cluttered it was to have wires going across the lab bench from the meter to electrode and another for the temperature probe. Not only untidy, but you have to hold both of these in the sample at the same time as well as taking a reading on the meter with the other. TRUEscience ...
We were excited to hear about the logging capabilities of the The system works by the pH smart cap taking the pH and temperature readings and relaying this to an android device. The App on the device expands measuring capabilities, connecting to the cloud and allowing the creation more enriched readings. Add images, attach GPS location, write notes and organise readings into jobs, the TRUEs...
The level of dissolved oxygen in wine is crucial in ensuring a long life, stable product which won't spoil or age rapidly.

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...
