Lovibond has two variations in its range of portable waterproof handheld meters. These electrochemical measuring instruments are designed for safety, mobility, and ease of data retention and storage.
The data loggers regularly save the collected measurement data which can be transferred to the computer via USB interface (serial or analogue).
With the SD 305/315/325 series, the instrument is ...
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....

Many pH meters also have a separate reading range which gives results in mV. This can be used for a range of applications.
1.) Checking your pH electrode calibration. Most meters automate the calibration of pH which makes it simple to perform and ensures consistency in results. However, when issues ar...
REDOX Measurement
Essentially a REDOX electrode is very similar to a pH one.The electrochemical potential developed by the REDOX indicator electrode is measure compared to a stable reference potential provided by the reference electrode. A standard silver chloride type reference electrode used in the TRUEscience combination electrode exhibits potentials on the hydrogen scale of +120mV at 15º...
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...

OSMOSIS
Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached. Reverse Osmosis (RO) is a membrane process of purific...
Thanks for sharing such a great information.. It really helpful to me.. I always search to read the quality content and finally i found this in you post. keep it up!
I came across your article about "DPD Tablets" on Camlab Info, and it's a valuable resource for anyone seeking information about water testing and analysis using DPD tablets. Your explanation of their usage and significance in water quality monitoring is quite informative.
This article on nanocolor tube tests is a gem for analytical enthusiasts. The idea of zero calibration is intriguing, and your detailed explanation makes it accessible. The step-by-step process helps demystify the technique for beginners like me. The use cases you've highlighted, particularly in...
Grant have introduced the new Controlled Rate Freeze Thaw (CRFT), which is a liquid nitrogen and cryogen free controlled rate freeze and thaw system for cryopreservation in a wide range of applications. Cryopreservation is a process where biological materials such as cells, tissues...
A dipslide is a means of testing the microbial content of liquids. This is a common method of monitoring and measuring microbial activity within many systems and commonly cooling systems. Usually the use of a dipslide is the first line of defence for the testing of microbial issues that could be...
Purchasing items using donated funds without the burden of VAT will now save many Millions of pounds each year which can be put to better use in advancing scientific knowledge to provide new treatments and cures that will shape the medicines of the future.
Working with pressure/vacuum conditions in the lab is common but not all products are designed to withstand this. Products with appropriate geometry and wall thickness are suitable for working safely with pressure. For example, filtering flasks, desiccators, or flat flange vessels, as well as...
