pH Mini Controller
with 4-20 mA Recorder Output

  • It’s easy to handle
  • Fire retardant casing
  • Selectable overdose protection system
  • Splash resistant cover

The BL 931700 mini pH controller has been designed for easy, affordable installation in tight spaces to perform simple yet effective process control. Thanks to its compact size, the BL 931700 mini pH controller can be installed right next to tanks or vats.

This versatile controller is ideal for a wide variety of applications, such as textiles, papers, photographic solutions, plating baths, chemicals and water treatment.This

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
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 overdosing.

In addition, this model features a 4-20 mA analog output for recorder connection.

Order Information:
BL 931700-0 (12 VDC) and BL 931700-1 ( 115/230V) are supplied with mounting brackets, transparent cover and instruction manual.
