AX400

The AX400 series

The AX400 analyzers incorporate the latest technology to

provide highly reliable, flexible, feature-packed devices that

satisfy a diverse range of process monitoring and control

applications. The complete range encompasses solutions for

pH/Redox (ORP), conductivity and dissolved oxygen.

Models AX41x and AX45x enable continuous measurements

of one or two low-level conductivity points with simultaneous

local display and retransmission. The analyzers are used with

ABB 2-electrode conductivity cells providing measurements

with exceptional accuracy and performance.

Model AX45x analyzers are dedicated to United States

Pharmacopoeia <645>.

AX400 Series analyzers are available for either wall-/pipe- or

panel-mounting and are rated to IP65.

High functionality as standard

All versions are supplied with two fully-isolated current

outputs as standard, that can be assigned to the measured

parameter, the sample temperature or any appropriate

calculated variables.

Three programmable relay set points are available that can

also be assigned as required.

Innovative features such as a power saving display and a

diagnostic current output option all contribute to low cost of
