The HI98318 is Hanna Instruments' latest waterproof pocket meter for measuring the EC/TDS of a hydroponic nutrient solution. Automatic calibration is achieved easily. Simply submerge the sensor in a 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.
This meter is only 0.7" thick and extremely ergonomic, fitting comfortably in your hand. It 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.
