Resistivity Mini Controller - BL983314-115/230VAC

$565.95

The BL983314 is a simple to operate resistivity controller designed for ultra pure water, reverse osmosis, and water conditioning applications. The BL983314 resistivity controller is also ideal for continuous monitoring to process solutions. Setpoint and calibration are manually adjusted with a trimmer and the alarm relay allows for simple control.

  • Fire-retardant casing
  • Selectable overdose protection system
  • Splash-resistant cover

About the BL983314 Resistivity Mini Controllers

Readings are automatically temperature compensated with three different coefficients (β=2.4, 3.5 or 4.5 %/℃). The alarm contact can be used for connection to an alarm, pump, solenoid or dosing system.

The relay contact is open when readings are higher than the setpoint, while for measurements lower than setpoint, the relay contact is closed. The hysteresis is typically 0.20 Mω •cm from the setpoint.

Measurements are displayed on the LCD and the multi-coloured LED continuously indicates if the controller is in measurement, dosing, or alarm mode. Users can choose automatic or manual dosing mode with a switch on the front panel. Manual control is particularly useful during maintenance operations, because it permits operators to enable or disable the dosing relay according to need.

The overtime control system advises users when the relay is active for too long, helping to prevent over-dosage.
