<p><span style="font-size: 16pf; color: #000000;">An electrical&nbsp;conductivity meter&nbsp;(EC&nbsp;meter) measures the electrical&nbsp;conductivity in a solution. It has multiple applications in research and engineering, with common usage in hydroponics, aquaculture, aquaponics, and freshwater systems to monitor the amount of nutrients, salts or impurities in the water. We supply conductivity meter with calibration certificate.</span></p>
