390a Digital Salt Tester. Measure Total Dissolved Solids (TDS), salt and temperature for food, water quality and HVAC maintenance. Easy-to-read LCD display. Measures temperature, TDS concentration and salt levels in solutions.
- Water: Test TDS levels to determine purity
- Food: Test the amount of salt in food, seafood, or processed foods
- Health: Monitor the amount of salt intake
- Water Filtration: Test for TDS to determine performance level of filtration systems
- Pools & Spas: Monitor TDS levels to prevent maintenance problems
- Test condensate water in cooling tower and humidifier reservoir applications to prevent bacterial growth
- Test TDS levels in make-up water to prevent scale formation, corrosion, and embrittlement
- Reduce water and chemical consump tion in boilers and cooling towers
- Determine when to perform blowdown and add make-up water
- Prevent contamina tion and corrosion of control valves, heat exchangers, and steam traps
- Verify automated TDS contollers are functioning properly
- Prevent low quality wet steam generation in boilers due to foaming caused by high TDS levels
390a Digital Salt Meter. Measure Salt Concentration and Temperature.
- The 390a measures the concentration of dissolved NaCl/TDS in liquids.
- Simply immerse the tip into liquids to determine the NaCl/TDS content and temperature
What is TDS (Total Dissolved Solids)?
TDS is the sum of all inorganic particulate material.
- Water contains a variety of minerals and salts, such as calcium, magnesium, carbonate, chloride and nitrate etc.
- TDS is the parameter used when measuring the total sum of all these compounds in water.
- TDS is an indicator used for wastewater analysis and measuring mineral content of water.
