Groline Nutrient Tester - HI98330

The HI98330 nutrient tester is designed to measure the conductivity of the nutrient solutions used in agriculture and hydroponic applications. Features at-a-glance: IP67 waterproof and floating design No user calibration needed Auto-on when placed in nutrient water Auto-off 30 seconds after stable measurement   Accurately Measure Electrical Conductivity 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. Extended Range 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). IP67 Waterproof Rating The IP67 waterproof rated and floating casing houses the EC graphite electrodes and temperature sensor, and is suitable for stirring and testing simultaneously.   Additional Features and Benefits: 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) 6-year warranty Wide EC range Specification Name Detail SKU HI98330 EC Range 0.2 to 6.0 mS/cm EC Resolution 0.1 mS/cm (0.2 to 4.0 mS/cm); 0.25 mS/cm (4.0 to 6.0 mS/cm) EC Accuracy 0.1 mS/cm (0.2 to 4.0 mS/cm); 0.25 mS/cm (4.0 to 6.0 mS/cm) TDS Range 100 to 3000 ppm (500 ppm scale)140 to 4200 ppm (700 ppm scale) TDS Resolution 50 ppm (100 to 2000 ppm)125 ppm (2000 to 3000 ppm)70 ppm (140 to 2800 ppm)175 ppm (2800 to 4200 ppm) TDS Accuracy ±4 % of reading ±1 resolution point EC/TDS Probe Graphite sensors in ABC + PC body Automatic Shut-Off Auto-off 30 seconds after stable measurement Battery Type / Life 3× 1.5V AA alkaline / Approx. 3 years (10 measurements/day) Environment 0 to 50 °C (32.0 to 122.0 °F) Dimensions 444 mm (17.48”)Ø 30 mm (1.18”) Weight 265 g (9.3 oz.) w/ batteries Ordering Information HI98330 is supplied with quick reference guide with instrument quality certificate.
