Certification
Canadian Radio Interference-Causing Equipment Regulation,
IECS-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 numèrique 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.
Product overview
This instrument counts airborne particles with a laser diode light source
and collection optics. Refer to Figure
particle counter by an attached, external vacuum system.
Multiple instruments can be installed at different locations in a clean
room to monitor the air quality. Count data is sent to the user-supplied
central monitoring software through the applicable communication
protocols. The central monitoring software is used to remotely operate
the instrument.
The sensor flow path is resistant to vaporous hydrogen peroxide (VHP)
for VHP-based standard clean room disinfection and cleaning cycles.
