Why Water Quality Matters

Whether you're maintaining a hydroponic garden, managing a pool or spa, caring for an aquarium, or ensuring your drinking water is safe, understanding total dissolved solids (TDS) is crucial. The Hanna HI98301 DiST 1 Waterproof TDS Tester makes professional-grade water testing accessible, accurate, and incredibly simple.

What is TDS and Why Should You Measure It?

Total Dissolved Solids (TDS) refers to the combined content of all inorganic and organic substances dissolved in water, measured in parts per million (ppm) or milligrams per liter (mg/L). High TDS levels can indicate:

• Excess nutrients in hydroponic systems
• Mineral buildup in pools and spas
• Water hardness affecting aquarium inhabitants
• Potential contaminants in drinking water

Perfect Applications

Hydroponics

Monitor nutrient solution strength to optimize plant growth. The HI98301 helps you maintain the ideal TDS range for different growth stages, preventing nutrient burn or deficiency.

Pool & Spa Maintenance

Track dissolved solids to prevent scaling, cloudy water, and equipment damage. Regular TDS monitoring tells you when it's time for partial water changes.

Aquarium Care

Ensure a healthy environment for fish and coral by monitoring mineral content. Different species thrive at different TDS levels—the HI98301 helps you dial in the perfect parameters.

Drinking Water Quality

Test tap water, well water, or filtered water to verify purity. The EPA recommends TDS levels below 500 ppm for drinking water.
