BL 931700 is provided with a selectable set point for acid or basic dosage.

Measurements are directly taken from a pH electrode in the range from 0 to 14 with a 0.01 pH resolution. Accuracy is ensured by two point calibration, performed manually through trimmers on the front panel.

Users can choose automatic or manual dosing mode with a switch on the front panel. Manual control is particularly useful during maintenance operations, because
