Ideal for hydroponics and agriculture applications, the HI98330 GroLine® Nutrient Tester accurately measures the electrical conductivity (EC) in mS/cm and the total dissolved solids (TDS) conversion in parts per million (ppm) of the nutrients in water.
Suitable for plants that need a higher EC, the tester features an extended range up to 6.0 mS/ cm (EC), 3000 ppm (500 ppm scale), and 4200 ppm (700 ppm scale).
The IP67 waterproof rated and floating casing houses the EC graphite electrodes and temperature sensor, and is suitable for stirring and testing simultaneously.
