BAMOPHAR 323 Bamo Conductivity / Resistivity

BAMOPHAR 323 Bamo Conductivity / Resistivity is equipped with a color touch screen for the display of a multilingual menu friendly and intuitive. It provides easy reading of measurement, temperature, and state of the thresholds.

It displays a menu with all parameters for configuration of analog outputs, thresholds set up, and regulation mode. In order to facilitate its commissioning, a programming menu can simulate the measurement, acting on the analog outputs, as well as on the thresholds.

Associated measuring cells have cell factors from 0.01 up to 10 for accurate measurements between 0 to 2 µS/cm and 20 mS/cm or O to 200 Ω.cm and 200 MΩ.cm. BAMOPHAR 323 displays an absolute or compensated temperature measurement (Access to two reference charts: 20 °C and 25 °C).

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

  • Allows a second measuring parameter (pH, flow-rate, turbidity, etc.) Data from this blind unit are displayed on the main unit
  • Connected to main unit via a 4 wire shielded cable (Cable length between both devices: max. 500 m) • RS422 and Data Logger of main unit are shared between both units.
