Hanna Instruments BL983324-0 TDS Mini Controller, 0.0 - 49.9 ppm, 12Vdc, 0.1 ppm

BL 983324 is a panel mounted TDS controller, designed for easy installation, configuration and maintenance. The meter is provided with a dosing relay, activated when the TDS reading exceeds the set point value. Measurements are compensated for temperature variations and shown on the display automatically. A multicolored LED on the front panel continuously indicates if the mini controller is in measurement, dosing or alarm mode. Wiring and external device connections are extremely simple to perform through the terminals on the rear of the instrument. 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 advises operators when the relay is active too long, helping to prevent over dosage. This model is supplied with mounting brackets, transparent cover and instruction manual. Range: 0.0 to 49.9 ppm. Resolution: 0.1 ppm.
