Applications of the digital water tester

  • Aquaculture and aquarium: A constant level of minerals is necessary for aquatic life. The water in an aquarium or tank should have the same levels of TDS and pH as the fish and reef’s original habitat.
  • Hydroponics: (TDS is the best measurement of the nutrient concentration in a hydroponic solution.)
  • Window Cleaning / Carwash: TDS levels must be monitored to prevent maintenance problems.
  • Industrial: High TDS levels could impede the functions of certain applications, such as boilers and cooling towers, food and water production and more.
  • Food & Beverage: For a truly great cup of coffee, proper TDS levels must be maintained.
  • Water Treatment: Hardness (and Water Softeners) – High TDS indicates Hard water, which causes scale buildup in pipes and valves, inhibiting performance.
  • Colloidal silver water: TDS levels must be controlled prior to making colloidal silver.
  • Taste/Health: (High TDS results in undesirable taste which could be salty, bitter, or metallic. It could also indicate the presence of toxic minerals. The EPA’s recommended maximum level of TDS in water is 500mg/L (500ppm).)
  • Filter performance: Test your water to make sure the reverse osmosis or another type of water filter or water purification system has a high rejection rate and know when to change your filter (or membrane) cartridges.
