Hanna Combo PH-EC meter allows us to measure accurately and continuously the values of EC, pH and temperature in the irrigation tank. This tool is really effective, especially in hydroponic or aeroponic systems re-circulation, as the above values are subject to fluctuations.
The control unit is in a mounted IP54 housing which is resistant to water jets and sprays. The pH electrode is replaceable and can be calibrated at one or two points. As for the EC, it is calibrated at a single point.
Hanna Combo PH-EC Tester enables you to select a point of measurement, a warning through a LED when the selected value changes. The selection point PH varies between 3.0 and 7.0 and the LED indicates when the pH is greater than the selected value. The LED flashes if the EC is less than the selected, comprising from 1.00 to 3.50 mS/cm (EC).
