2.5 Product overview

Chemical or biological hazards. If this instrument is used to monitor a treatment process
and/or chemical feed system for which there are regulatory limits and monitoring
requirements related to public health, public safety, food or beverage manufacture or
processing, it is the responsibility of the user of this instrument to know and abide by any
applicable regulation and to have sufficient and appropriate mechanisms in place for
compliance with applicable regulations in the event of malfunction of the instrument.
The sodium analyzer continuously measures very low concentrations of sodium in ultra-pure water.
Refer to Figure 1 and
The sodium analyzer is available with or without an enclosure. The analyzer with an enclosure is for
wall, panel or table mounting. The analyzer without an enclosure is for panel mounting. Refer to
Figure 1.
The sodium analyzer uses a sodium ISE (ion specific electrode) electrode and a reference electrode
to measure the sodium concentration of the water sample. The difference in potential between the
sodium and reference electrode is directly in proportion to the logarithm of sodium concentration as
shown by Nernst law. The analyzer increases the pH of the sample to a constant pH between
10.7 and 11.6 with a conditioning solution before the measurement to prevent interference from
temperature or other ions on the sodium measurement.
The door can be easily removed for better access during installation and maintenance procedures.
The door must be installed and closed during operation. Refer to
