Tips: What is salt in water quality tester?
Salt concentration in water directly impacts its quality, affecting physical, chemical, and biological properties. High salinity can alter water taste, hinder plant growth by interfering with nutrient uptake, and harm aquatic life, especially freshwater species not adapted to salt. In aquaculture, precise salt levels are essential for marine species' health and growth. Elevated salt concentrations can also corrode infrastructure, complicating water treatment. The Smart Water Quality Tester measures salt levels from 0.01% to 25% or 0–9999 ppm, enabling effective monitoring for applications like water treatment, desalination, and aquatic ecosystems. Accurate salt measurement is key to maintaining optimal water quality across diverse environments.
