2-in-1 digital pen type water quality tester. Measure TDS, Conductivity and temperature of your liquid sample in one handy unit.
Total Dissolved Solids (TDS) measured in ppm (parts per million) is key factor in water quality analysis, water with high level of TDS is not safe for human consumption. On the other hand EC measures the electrical conductivity in a solution. This two parameter 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.
