Liquid conductivity meter review

The measurement of a solution’s ability to conduct electricity is called conductance. All aqueous solutions conduct electricity to some extent. Using electrolytes like salts, acids or bases to transparent water helps boosts the conductivity and naturally decrease the resistance. 


Liquid Conductivity

  • It is a measurement of charged particles, known as ions which freely roam around in the liquid.
  • More the ions, more the conductivity
  • Liquids containing compounds which completely break apart into ions also have high conductivity.
  • It is highly dependent on temperature.  Unlike metals, increase in temperature results in the increased conductivity of the electrolytes.

Note: Conductivity meters must be compared with the standards to provide accurate results.
It is very important to accurately determine the conductivity of any liquid so as to find out what is the electric strength of a liquid or what amount of electricity it can accommodate. For that purpose a metric device is required to tell that up to what extent, the liquid is conductive; in other words, the conductance.. That device is called liquid conductivity meter.


Conductivity meter

A conductivity meter precisely measures the amount of electrical current or conductance in a solution. It shows the condition and health of the water body by examining the amount of nutrients, salts or impurities in it.
This meter also measures changes in waste water processes at water treatment plants. Conductivity meters are a routine affair device used in environmental laboratories or any water treatment plant.
