description

The GroLine waterproof EC/TDS meter for hydroponics is a simple way to measure fertilizer concentration in a nutrient solution.

The HI98318 EC/TDS tester features a graphite sensor that reduces the polarization effect commonly found with amperometric meters with two stainless steel pins.

Automatic calibration is made easy. Simply immerse the sensor in the calibration solution and the instrument automatically recognizes the calibration values (5.00 mS/cm in quick calibration mode or 1.41 mS/cm in standard calibration mode). Temperature is automatically compensated with the built-in temperature sensor.
