Single and dual input analyzers for pH/Redox (ORP) AX416, AX436, AX460, AX466 & AX468 1 Introduction 1.1 System Description The AX460 single input and AX466 dual input 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.

Disconnect the Pt100/Pt1000/Balco 3K leads and connect a suitable resistance box directly to the analyzer inputs – see Section 6.4, page 50 (wall-/pipe-mount analyzer) or see Section 6.5, page 52 (panel-mount analyzer). Check the analyzer displays the correct values as set on the resistance box – see Table 8.2.
