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.
Description
The 390a measures the concentration of dissolved salt in percent and
Total Dissolved Solids (TDS) in ppm. Temperature in Celsius or
Fahrenheit is also measured.
Simply immerse the tip into liquids to determine salt content, TDS
level, and temperature.
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 filtra-
tion systems.
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 tow-
ers.
- Test TDS levels in make-up water to prevent scale formation, corro-
sion, and embrittlement.
- Determine when to perform blowdown and add make-up water.
- Prevent contamination and corrosion of control valves, heat exchang-
ers, 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.
