This versatile contoller is ideal for a wide variety of applications, such as textiles, papers, photographic solutions, plating bath, chemicals and water treatment.
HI-931700 is provided with a selectable setpoint for acid or basic dosage.
Measurements are directly aquired from a pH electrode in the range from 0 to 14 with a 0.01 pH resolution.
Accuracy is ensured by the 2 point calibration, performed manually through trimmers on the front panel.
You can also choose automatic or manual dosing mode 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.
The overtime control system advises you when the relay is active for too long, helping to prevent overdosing.
