BL-983315-1 TDS Mini Controller 0.00 to 199.9 mg/L

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 supply power to a dosing pump or a solenoid connected to a valve. The BL-983315 can also be used to monitor the quality of water produced from ion exchange, reverse osmosis (RO) or distillation.

The BL-983315 uses a 0.5 conversion factor in which 1.0 μS/cm = 0.5 ppm.

Adjustable Dry Contact Dosing Relay

The BL-983315 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.

Multi-colour LED Indicator

Multi-colour 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" (13mm) NPT Male Threaded Amperometric Probe for Mounting In-line*

The BL-983315 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.
