Description:

BL 981411 pH controller has been designed for easy, affordable installation in tight spaces, ideal for simple and effective process

Measurements are clearly displayed on the large 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. You can also

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 you to enable or disable the dosing relay according to your need. An overtime control system advises you

when the relay is active too long, to help prevent overdosing.

Two models are available, with power supply input at 115/230 Vac or 12 Vdc.
