About the BL-983314 Resistivity Mini Controllers

Fire retardant casing
Selectable overdose protection system
Splash-resistant cover

Readings are automatically temperature compensated with three different coefficients (β=2.4, 3.5 or 4.5 %/°C). 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.
