HANNA®

GroLine Waterproof EC/TDS (ppm) Tester (Model HI98318)

The GroLine Waterproof EC/TDS Tester is made specifically for hydroponics, provides a simple, inexpensive solution to measure fertilizer concentration in a nutrient solution.

The HI98318 EC/TDS tester has a graphite sensor that reduces the polarization effect common with amperometric testers that use two stainless steel pins.

Automatic calibration is achieved easily.

Simply submerge the sensor in calibration solution and the meter will automatically detect the calibration standard (5.00 mS/cm in Quick Cal mode or 1.41 mS/cm in standard calibration mode).

Temperature is automatically compensated for with the integrated temperature sensor.

Comes with GroLine EC/TDS meter is supplied with protective cap, (4) HI50036 Quick Cal Calibration Sachets (20 ml), (1) CR2032 battery, instruction manual, and quality certificate.
