BL-983320-1 Conductivity Mini Controller (Range 199.9 µS/cm) information

Hanna's extended description

These meters permit automatic control of installations previously checked manually.

EC measurements are shown on the large display and the multi-coloured LED continuously indicates if the mini controller is in measurement, dosing or alarm mode. BL 983313 measures in the 0 to 1999 µS/cm range, BL 983320 measures from 0.0 to 199.9 µS/cm and BL 983322 from 0.00 to 19.99 µS/cm.

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 over dosage.

Order Information:

The BL 983320 is supplied with mounting brackets, transparent cover, and instructions.

The electrode HI-7640-00 must be purchased separately.
