The GroLine waterproof EC / TDS tester is specially designed for hydroponic cultivation, provides a simple and convenient solution to measure the concentration of fertilizers in nutrient solutions, equipped with a graphite sensor that reduces the polarization effects typical of amperometric testers that use two stainless steel pins. Automatic calibration is an easy procedure Simply dip the sensor into the calibration solution and the instrument will automatically detect the calibration standard (at 5.00 mS / cm in quick calibration mode or at 1.41 mS / cm in standard calibration mode). The temperature is automatically compensated by the built-in temperature sensor.
- Automatic temperature compensation with the integrated temperature sensor
- Graphite sensors that reduce polarization phenomena EC / TDS conversion factor selectable between 0.5 (500 ppm) and 0.7 (700 ppm)
- One-point automatic calibration using the quick calibration standard solution or at 1.41 mS / cm in standard calibration mode
- Battery life up to 250 hours
