Conductivity controller-transmitter Alpha COND 2000

Conductivity controller/transmitter Alpha COND 2000

Features of Conductivity controller-transmitter Alpha COND 2000:

  • Measures seven ranges, from 0 to 2 µS/cm to 0 to 1000 mS/cm.
  • Readings of up to three-decimal resolution at ±1 % accuracy.
  • Adjustable temperature coefficients for more precise temperature compensation: Choose between programmable linear temperature compensation from 0.0 % to 10.0 %, and pure water temperature compensation to correct
    non-linearity of ultrapure water temperature correction curves.
  • Meter displays electrode status after each calibration
  • User-adjustable cell constant values (k = 0.005 to k = 9.999).
  • 4-cell electrode prevents polarizing effects and
    electrode fouling in samples with high conductivity.
  • Accepts 2- or 3-wire, Pt100 or Pt1000 RTD sensors for automatic temperature compensation.
  • Allows user to input cell constant corresponding to connecting electrode independently during calibration.

Applications

Conductivity controller-transmitter Alpha COND 2000 is used in:

General: Use for virtually any batch or online applications where rapid, accurate control. Great for OEM/system integrator.

Industrial: Use in applications involving agriculture, chemical processing, boiler and water heaters, wafer-fab, microprocessor manufacturing, pharmaceuticals, pulp and paper industries, and bleach manufacturing.

Water Purification/Treatment: Use to treat batches of incoming process water, ultrapure water, boiler and feed water control.

Regulatory: Hook to recorder to document data for regulatory compliance.
