  • Automatic hold function of the measurement result
  • Measures EC or TDS in PPM
  • Temperature reading
  • Dual Range : 0-999ppm with dissolving of 1 ppm - 1000-9900 with dissolving of 10 ppm
  • Accuracy ± 2%
  • Large, easily readable LCD Display
  • Simple operation
  • 2 x 1.5v button cell (AG13) Batteries included
  • Protective Case included
  • User manual

TDS (Total Dissolved Solids) measures the concentration of dissolved inorganic salts and organic matter in water, expressed in ppm (parts per million), which is equivalent to mg/L. Ideal drinking water typically ranges from 50-500 ppm, while levels over 1,000 ppm are generally considered poor quality, and above 2,000 ppm are unsafe

TDS in hydroponics optimal levels usually range from 500 to 1500 ppm, varying by plant type and growth stage roughly 500-800 ppm for seedlings and 1000-1500 ppm for mature, fruiting plants. 

Key PPM Ranges and Guidelines:
  • Seedlings/Cuttings: 100–250 ppm
  • Young/Leafy Greens (Lettuce): 500–800 ppm
  • Mature/Fruiting Plants (Tomatoes): 1000–1500 ppm
  • High Nutrient Need (Broccoli): 1750-2450 ppm
