These Hanna Instruments have been designed for TDS control in hydroponics, horticulture and water conditioning.

Thanks to their compact size, they 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 large display and the multicoloured LED continuously indicates if the minicontroller is in measurement, dosing or alarm mode. BL 983321 can control TDS from 0.00 to 19.99 ppm and BL 983329 from 0 to 999 ppm. You can also choose automatic or manual dosing mode with a switch on the front panel. Manual control is particularly useful during maintenance operations, because it permits you to enable or disable the dosing relay according to your need. The overtime control system advises you when the relay is active for too long, helping to prevent overdosage. Models are available with power supply input at 115/230 Vac or 12 Vdc.
