This instrument has been designed for TDS control in hydroponics, horticulture and water conditioning. Compact in size, it can be mounted in confined spaces or even right next to the vat or barrel containing the chemicals. These meters permit automatic control of installations previously checked manually.
Readings are shown on the display and the multicolored LED continuously indicates if the mini controller is in measurement, dosing or alarm mode.
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 your need.
The overtime control system advises users when the relay is active too long, helping to prevent over dosage.
