Understanding Your Readings

TDS (Total Dissolved Solids) – Measured in ppm

TDS reflects the concentration of inorganic and organic substances in water. The lower the TDS, the purer the water. Use the table below to interpret your readings:

EC (Electrical Conductivity) – Measured in µS/cm

EC indicates the ability of water to conduct electricity, which relates to the concentration of salts and minerals.

Applications

• Aquariums – Maintain optimal conditions for aquatic life
• Hydroponics – Balance nutrients for healthy plant growth
• Laboratories – Conduct precise water analysis
• Home Use – Check tap, bottled, or filtered water quality
• Water Treatment Systems – Verify filter performance

Stay in control of your water quality with this accurate, easy-to-use digital tester. Whether you're managing a hydroponic garden or testing your home’s drinking water, this device delivers peace of mind with every drop.
