Canadian Radio Interference-Causing Equipment Regulation, ICES-003, Class A:
Supporting test records reside with the manufacturer.
This Class A digital apparatus meets all requirements of the Canadian Interference-Causing
Equipment Regulations.
Cet appareil numérique de classe A répond à toutes les exigences de la réglementation canadienne
sur les équipements provoquant des interférences.
FCC Part 15, Class "A" Limits
Supporting test records reside with the manufacturer. The device complies with Part 15 of the FCC
Rules. Operation is subject to the following conditions:
1. The equipment may not cause harmful interference.
2. The equipment must accept any interference received, including interference that may cause
undesired operation.
Changes or modifications to this equipment not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment. This equipment has been tested
and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case the user will be required to
correct the interference at their expense. The following techniques can be used to reduce
interference problems:
1. Disconnect the equipment from its power source to verify that it is or is not the source of the
interference.
2. If the equipment is connected to the same outlet as the device experiencing interference, connect
the equipment to a different outlet.
3. Move the equipment away from the device receiving the interference.
4. Reposition the receiving antenna for the device receiving the interference.
5. Try combinations of the above.

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
Figure 2 for an overview of the analyzer components.
