Description

The Hanna mini controllers have been specially designed for water conditioning and growing applications. The BL-983320 is a compact, panel mounted, process controller for measuring electrolytic conductivity (EC) of a process stream that is within the 0.0 to 199.9 μS/cm range. The device features a large LCD with protective cover. Users may choose from automatic or manual dosing modes. Compact in size, they can be mounted in confined spaces or even right next to the vat or barrel containing the chemicals.

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-983320 can also be used to monitor the quality of water produced from ion exchange, reverse osmosis (RO) or distillation.


Adjustable Dry Contact Dosing Relay


The BL-983320 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-983320 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
