Страница: 2 / 9

1. Before Use
• Please carefully read the Operators Manual before using this meter.
• Clean the sensor area with a neutral detergent using a soft cloth or sponge before and after use.
2. Description
• The 390 measures the concentration of dissolved NaCl/TDS in liquids.
• Simply immerse the tip into liquids to determine the NaCl/TDS content and temperature.
3. Applications
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.
HVAC –
Test condensate water in cooling tower and humidifier reservoirs to prevent bacterial growth and drain line corrosion.
Reduce water and chemical consumption in boilers and cooling towers.
Test TDS levels in make-up water to prevent scale formation, corrosion, and embrittlement.
Determine when to perform blowdown and add make-up water.
Prevent contamination and corrosion of control valves, heat exchangers, and steam traps.
Verify automated TDS controllers are functioning properly.
Prevent low quality wet steam generation in boilers due to foaming caused by high TDS levels.
4. WHAT IS TDS (Total Dissolved Solids) ?
: 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.
