BL-983322-0 Conductivity Controller (Low Range@ 19.99 µS/c) information

Hanna's extended description

Users may choose from automatic or manual dosing modes. When in automatic mode the dry contact relay is activated when a reading is above the set point. The relay can be used to activate a solenoid that switches from one DI (deionised) tank to another or to open a valve that will allow lower EC water to flow into a tank being monitored in order to lower its EC. The BL-983322 can also be used to monitor the quality of water from DI tanks or from a distillation apparatus. The BL-983322 measures EC from 0.00 to 19.99 μS/cm.


Adjustable Dry Contact Dosing Relay

The BL-983322 features a dosing relay that is activated when the reading is above a user programmable set point.


Programmable Overdose Protection

For enhanced safety the mini controller can be programmed to deactivate the dosing relay if the set point is not reached within a specified time interval. The overdosing timer is programmable from 5 to 30 minutes or disabled.


Relay Control Override

With the flick of a switch the mini controller's relay can be disabled (Off), placed in control (Auto), or be activated for manual operation (On) which is useful for priming a dosing pump.


Multicolour LED Indicator

Multicolour LED indicator allows an operator to quickly check the status of the controller.


  • Green = Meter in measurement mode and reading is below the set point
  • Orange/Yellow = Reading is above the set point and the relay is activated
  • Blinking Red = Indicates an alarm condition such as when the maximum dosing time has been exceeded

  • Fuse Protected Dosing Contacts

    The relay dosing contact is rated for up to a 2A load and is fuse protected.


    Labelled Termination Connections

    Quick-connect terminal blocks are clearly labelled for easy connection to power, conductivity probe and relay that can be used to operate a dosing pump, valve, audible alarm, or light.


    1/2" NPT Male Threaded Amperometric Probe for Mounting In-line*

    The BL-983322 mini controller uses the HI-7634-00 conductivity probe that is available with different cable lengths.

    *HI-7634-00 is not included and must be ordered separately.


    Order Information:
