ABB AX460 and AX466 Single and Dual Input pH/Redox (ORP) Analyzers

ABB AX460 and AX466 Single and Dual Input pH/Redox (ORP) Analyzers

The AX400 Series pH/Redox (ORP) analyzers and associated electrode systems have been designed for continuous monitoring and control of pH and Redox (ORP). The electrode system can be standardized to the analyzer using the built-in calibration facility and a single point buffering facility provides easy re-calibration after initial standardization.

The analyzer is available in wall-/pipe-mount or panel-mount versions with either one or two programmable, pH or Redox (ORP) input channels, each with its own associated temperature input channel. When making temperature compensated measurements, the sample temperature is sensed by a resistance thermometer (Pt100, Pt1000 or Balco 3K) mounted in the electrode system.
