HI-98330
The Nutrient Tester EC/TDS is ideal for hydroponics and agricultural applications.
The HI-98330 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. Key features IP67 waterproof and floating design No user calibration needed Auto-on when placed in liquid Auto-off 30 seconds after stable measurement Rugged and doubles as a stirring stick Low battery warning Readings displayed by 24 brightly lit LED lights Conductivity scales and operational instructions printed on the tester body Easy to clean (detachable crown-shaped cap)
