GroLine Waterproof EC/TDS Tester Hanna HI98318 is specifically designed for hydroponics, offering a straightforward and cost-effective solution for measuring fertilizer concentration in a nutrient solution.

Equipped with a graphite sensor, the HI98318 EC/TDS tester reduces the polarization effect commonly encountered with amperometric testers using two stainless steel pins.

Calibration is simple and automatic. By submerging the sensor in the calibration solution, the meter automatically detects the calibration standard (5.00 mS/cm in Quick Cal mode or 1.41 mS/cm in standard calibration mode). The integrated temperature sensor ensures automatic temperature compensation.

Key Features:

  • Waterproof design
  • Fast Automatic Temperature Compensation with an exposed temperature probe
  • Graphite sensors to reduce polarization effects
  • Selectable EC to TDS conversion factors: 0.5 (500 ppm) and 0.7 (700 ppm)
  • Single-point automatic calibration using the Quick Cal standard or 1.41 mS/cm in standard calibration mode
  • 250-hour battery life
