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....
Oxygen can dissolve into wine throughout production causing wine oxidation which in small amounts can be beneficial to some varieties such as red wines, but in large amounts can shorten the wine's life and lower the quality. Being able to measure the dissolved oxygen throughout wine production allows the winemaker to control and influence the amount of oxygen exposed to each variety before bott...
Ben studied Oenology and Viticulture at Plumpton college and now with his wife Hannah run Flint Vineyard in the beautiful Norfolk countryside. Throughout the wine production process the pH is tested; from measuring the grapes to decide when they are ready to ...
The SD 400 Oxi L is Oxygen meter which allows the measurement of dissolved oxygen (DO) at a high level. This is done thanks to the optical technology of luminescence. It uses an Optical DO probe which has distinct advantages: Low maintenance Easy calibration Fast response High accuracy The applications for this meter include: Waste Water Water Treatment Marine Water Surf...
What is a Redox Potential? Oxidation Reduction Potential (ORP or 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. When it tends to release electrons, it is a reducing system. When are Redox measurements required? There are a number of different reasons...
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 ...
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 golden rules to pH measurement is to routinely calibrate your pH meter before measuring any samples. pH buffers have a known pH value, most commonly 4, 7 and 10. Calibration with these buffers gives the meter reference points to use whilst measuring the pH of other samples. https://www.youtube.com/watch?v=0t240gykR_I The TRUEscience SMART cap system uses a bluetooth signal t...
The team at TRUEscience have had years of experience in supporting users of traditional pH meters. During their time they have seen all the frustrations that people have when using these meters - unclear buttons, difficult interfaces, trouble saving and retrieving results... Before, a user would take and save a set of pH measurements on their pH meter and later go back to analyse the results t...
Quality control (QC) checks are used to review the quality of production, processes and competence. It is essential to continuously test and challenge these aspects to ensure and maintain the highest quality process as possible. [caption id="attachment_11361" align="aligncenter" width="794"] TRUEscience pH Meter[/caption] For pH measurement, performing a QC check allows you to have an additio...
