General Catalog 106-01
pH-Meter and mV-Meter

  • pH/ORP programmable monitor and regulator
  • Alphanumeric back lighted LCD display
  • Friendly using menu
  • Scales:
    0 - 14 pH and ± 1000 mV
    through configuration
  • Temperature compensation Automatic or manual
  • 2 analogical outputs 0/4-20mA galvanic insulated
  • 4 relay outputs (Normally Open contacts)
  • 1 input to switch the regulation on Stand-by
  • 2 models available:
    Panel mounting 72 x 144
    Wall mounting IP 65
    RS 422 /J-BUS + LOGGER
    Extension for 2nd measurement input

An extension terminal (wall, panel mounting or DIN rail mounting):

  • Allows a second measurement parameter (pH, Conductivity, Chlorine, Turbidity, Flow, and 4-20 mA, depending of the model)
  • The data from this blind device are displayed on the main device (second line display).
  • A 4 wires shielded cable is necessary to link both devices (maximum length of 500m)
  • The options RS422 and the data logger are shared between both Bamophox.

The BAMOPHOX 106 offers high flexibility on use mixing different built-in programmes for regulation, thresholds, temperature compensation, and alarms.

The 2 lines back lighted display, 16 alphanumerical characters, gives an easy measurement and temperature reading in any conditions. It also displays the configuration menu and settings of thresholds, analogical outputs, operation data modes, calibration steps.

To allow a quick and easy diagnostic after configuration a simulation program is built-in with direct actuation on contacts outputs, analogical outputs and PID regulation.

A copy of the signal IS AVAILABLE on the 4-20 mA output (galvanic insulated); it can be set up within the all range of the parameter.

Temperature measurement is also available on a 4-20 mA output (this output is not available when PID regulation is in use).
