The Groline EC/Temperature Tester is the latest Hanna handheld device tailored for gauging the EC/TDS levels in hydroponic nutrient solutions. Its user-friendly design ensures comfortable handling, while the large LCD screen displays EC/TDS and temperature readings, as well as calibration status and battery level. Operating this device is simplified with just two buttons: one for power and the other for automatic one-point calibration.

Designed specifically for hydroponic applications, the GroLine Waterproof EC/TDS Tester offers a straightforward and cost-effective solution for measuring fertilizer concentration in nutrient solutions.

Unlike traditional amperometric testers with two stainless steel pins, the Groline EC/Temperature Tester features a graphite sensor that minimizes the common polarization effect.

Calibration is hassle-free: simply immerse the sensor in the calibration solution, and the device automatically identifies the calibration standard (either 5.00 mS/cm in Quick Cal mode or 1.41 mS/cm in standard calibration mode). Temperature compensation is automatic thanks to the integrated temperature sensor.

Key Features:
