BI-650 Industrial Conductivity Controller


Conductivity and Total Dissolved Solids.


  • Economical online conductivity controller contains the TDS measurement mode.
  • 1 to 3 points push-button calibration, automatically recognizes the calibration solutions.
  • Selectable cell constant (0.1/1/10), temperature coefficient and TDS conversion factor.
  • Automatic Temperature Compensation provides accurate reading over the entire range.
  • Low or high alarm limit can be set by user and automatically activate an external device.
  • 4 to 20mA output signal meets industry standard.
  • Manual temperature calibration corrects the temperature deviation.
  • Setup menus allows setting the 9 parameters, including the number of calibration points, temperature unit, alarm limits, hysteresis value, etc.
  • Reset feature automatically resumes all settings back to factory default options.
