GroLine Nutrient Tester

The GroLine Nutrient Tester HI98330 by HANNA Instruments is designed to measure the conductivity of the nutrient solutions used in agriculture and hydroponic applications. Ideal for hydroponics and agriculture applications, the 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. Accurately Measure Electrical Conductivity IP67 waterproof and floating design No user calibration needed Auto-on when placed in nutrient water Auto-off 30 seconds after stable measurement 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. Rugged and doubles as a stirring stick Low battery warning Readings
