Hanna Instruments GroLine Waterproof EC/TDS/Temp Tester

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 GroLine Waterproof EC/TDS Tester is one of Hanna Instruments' latest pocket meters for measuring the EC/TDS of a hydroponic nutrient solution. This modern looking meter is only 0.7" thick and extremely ergonomic, fitting comfortably in your hand. The GroLine Waterproof EC/TDS Tester has a very large easy to read LCD display that shows both EC or TDS and temperature along with calibration, stability, and low battery indicators. All operations are simplified to two buttons. One is for turning the meter on/off and the other for automatic one point calibration. The GroLine Waterproof 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.
