What is salinity?

Salinity refers to the concentration of dissolved salts (mainly sodium chloride, but also other salts such as magnesium and calcium compounds) in water. It is usually expressed in parts per thousand (ppt) or milligrams per liter (mg/L).

Why is salinity monitored with pocket testers?

The measurement of salinity is crucial in various areas:

  1. aquaristics & marine aquariums - corals and marine life require constant salinity for healthy growth.
  2. agriculture & irrigation - Excessive salinity in water can affect plant growth and degrade soil quality.
  3. drinking water treatment - high salinity can make water undrinkable and pose health risks.
  4. food industry - control of salt content in products such as brine, fermented foods or beverage production.
  5. industrial applications - monitoring in cooling circuits, seawater desalination or chemical processes.
  6. environmental monitoring & oceanography - checking salinity in rivers, lakes and oceans to analyze climate change and water quality.

Advantages of pocket testers for salinity measurement:

  • Fast & mobile measurement without the need for a laboratory
  • Easy to use for hobbyists and professionals
  • Precise control to prevent damage to plants, animals or technical systems
