Conductivity (also called electrical conductivity or EC for short) is a measure of a substances ability to conduct an electrical current and this can be measured using a conductivity meter. In the farming and the agriculture industry, conductivity can be used as an indicator of overall soil nutrient levels.

What is conductivity? Conductivity is a measure of the ability of a substance to conduct an electrical flow through it. In water, many compounds and molecules (such as dissolved salts and inorganic materials) dissociate into constitutive ions. Ions are small sub-atomic particles and carry with them an electrical charge; either positive (cations) or negative (anions). These particles help condu...
The portable FiveGo range by Mettler Toledo have had a re-design. They are now available with IP67 waterproof protection whilst still maintaining ergonomic design and intuitive operation. There are three meters in the range to cover pH, Conductivity and Dissolved Oxygen measurements. The FiveGo Design The large, well-structured display is great for easy viewing The LCD display ...
Mettler Toledo have released their new FiveEasy range of benchtop meters for pH and conductivity. The new models, still part of the FiveEasy family, have been redesigned and have had extra features added. We were impressed at the compact, clever design and the flexibility the new range offers. [caption id="attachment_8141" align="aligncenter" width="300"] The new FiveEasy range, but what ...
Laboratories using a deioniser system to generate deionised (or DI) water in house should test the water produced regularly, to ensure the system is working well and producing water of the required purity. [caption id="attachment_8125" align="aligncenter" width="300"] How can you test your DI water is pure enough?[/caption] Conductivity is usually used as a good indicator of the quality, ...
The Edge meter by Hanna Instruments can be used with one probe to measure either pH, conductivity or dissolved oxygen. For maximum flexibility this smart slim unit allows use on the bench top, as a handheld or in a wall mount - whichever is easiest for you.

Answer: Total Dissolved Solids (TDS) is a measure of the combined content of all the inorganic and organic substances such as mobile charged ions, minerals, salts or dissolved metals in a volume of liquid. Normally TDS is used in water testing, where TDS is defined as anything present that is not pure water (H2O) molecule or suspended solids. Finding out the exact amount of TDS in water ...
