This HANNA mini controller has been specially designed for water conditioning and growing applications. Compact in size, it can be mounted in confined spaces or even right next to the vat or barrel containing the chemicals. This meter permits automatic control of installations previously checked manually.
EC measurements are shown on the display and the multicolored LED continuously indicates if the mini controller is in measurement, dosing or alarm mode.BL 983320 measures from 0.0 to 199.9 µS/cm.
Users can choose automatic or manual dosing mode with a switch on the front panel. Manual control is particularly useful during maintenance operations, because it permits operators to enable or disable the dosing relay according to need. The overtime control system advices users when the relay is active for too long, helping to prevent over dosage.
