The BL 981411 pH controller has been designed for easy, affordable installation in tight spaces, ideal for simple and effective process control. The unit is provided with high impedance pH input and can be used with any pH electrode with standard BNC connector. Measurements are clearly displayed on the LCD, while the status LED indicates operating mode.

BL 981411 is also provided with a dosing relay. Selecting acid dosing, will cause the relay to activate when the measurement is higher than the set point. If the basic dosing is selected, the relay is activated when the reading falls below the set point.

Set point adjustment (from 0 to 14 pH) and calibration procedures are easily performed with trimmers on the front panel. Users can choose from automatic or manual dosing modes 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. An overtime control system advises users when the relay is active too long, to help prevent overdosing.
