In everyday life, the question is rarely asked, "What is conductivity?"
With the introduction of the SI system of units, "electrical conductivity" became the standard formal term, but in practice the word "conductivity" alone is often used.
Since conductivity is an indicator of how easily current flows through a solution, it depends on the amount of ions and their mobility in that solution.
Conductivity is a measure of how easily electricity can flow. In water, it is the ions that carry the current from one to another. That is, the more Na+ and Cl- there are in the water, the more current is carried, and the higher the conductivity. So if we know the conductivity of a salt water sample, we can calculate how salty the water is. (This is done when converting the salinity to get the value displayed by the Twin conductivity meter).
In summary, the following can be stated: Conductivity is a measure of the ability of a solution to conduct electric current. It is expressed as microsiemens (micro-Siemens per centimeter or µS/cm) or, in higher conductivity levels, as millisiemens. It is also the reciprocal of resistivity. Some industries, such as water treatment, have adopted a measurement known as TDS (Total Dissolved Solids). The TDS value is approximated to conductivity using a multiple factor and is expressed in parts per million (ppm).

Our The XS Instruments PC 7 Vio and 70 Vio handheld pH, millivolt, oxidation-reduction potential, conductivity, dissolved solids and temperature multiparameter meters with innovative high-resolution colour display are suitable for working in all conditions and offer you an integrated user-friendly guide in the form of the set-up and calibration mode. This allows for easy and intuitive use of the instrument by the user at any time, no matter how much experience the user has in handling the equipment. The PC 7 Vio and the PC 70 Vio, has an automatic pH calibration with USA and NIST buffers with up to three points for pH and one point for ORP. For the calibration of the conductivity electrode, you have up to five fixed points, as well as an individual calibration point. You are supported by intuitive symbols on the backlit screen, including display of the measurement stability (adjustable) and any errors. Another advantage is that you receive the multi-parameter measuring device in our professional measuring case, which contains the selected measuring electrodes, as well as our respective buffer solutions and the instructions. Complementary advantages of the 70 Vio version:GLP functions: Date and time, recall of calibration data and "Calibration due" function Integrated data logger for up to 1000 data, automatic and manual PC connection via USB for evaluation of measurement data (Micro-USB on the instrument side) via Data Link+ software Automatic brightness control of the display (prolongs battery life) Only 6 keys for easy control of all functions of the unit 230V power supply unit Manufacturer article number: 50110712
