ABB AX411 Single and dual input analyzers for low level conductivity
Description
Significantly Reduced Maintenance Costs
The AX400 Analyzers are supplied as standard for 85 to 265V AC operation. There are no inner switches to set.They can also be provided for 24V AC or 12 to 30V DC supply and recognize automatically which of the two supplies is being used. 24V DC operation reduces maintenance costs significantly by negating the need for costly, yearly safety tests to ensure compliance with safety procedures.
Energy Saving Display The backlit display has been designed to operate in all types of
environments and shows both the measured parameter(s) and,on a separate 16-character display line, diagnostic and computed information.On dual-input analyzers both measured parameters are displayed simultaneously.For conservation of energy, the backlight can be set to switch off automatically after 60s of inactivity.

Single and Dual Input Analyzers
Both single and dual-input analyzers provide accurate
measurement of low-level conductivity and can be configured
for ranges in µS cm–1, µS m–1, mS cm–1 and mS m–1.
Alternatively, the instrument can be set up for resistivity in
MW-cm, total dissolved solids and salinity.
In addition, the dual-input analyzer calculates, displays and
transmits:
Ratio of Cell 1/Cell 2
Difference Cell 1 – Cell 2
Passage (Cell 1/Cell 2) x 100
Rejection (1 –[Cell 1/Cell 2]) x 100
Inferred pH
These facilities are invaluable tools for demineralization and
reverse osmosis and a host of industrial processes.

Cation Conductivity and Inferred pH
Measurement
In low conductivity, ammoniated boiler waters, the AX411
analyzer can calculate an inferred pH measurement from the
conductivity and a preset ammonia concentration. With this
method, one AX411 provides cation conductivity, a direct output
of pH, reduced cost and none of the maintenance associated
with pH electrodes.
Self-monitoring of the validity of the pH measurement is
achieved by checking that an after-cation conductivity value is
sufficiently low. This measurement is provided by the second
input of the AX411 analyzer. Alarm contacts can be configured
for cation conductivity, invalid pH and exhausted resin.
