Standard System
The standard model Q46H/65 system includes three main components, the Q46H analyzer, a
constant head flow cell, and a ClO
2
sensor. A sealed flowcell is also available for applications
where sample flow rate and pressure can be carefully controlled. Figure 1 shows a typical
installation.
For connection of the sensor to the electronics, a 25 foot cable is supplied. An additional 100 feet
of interconnect cable may be added using #07-0100 junction box. All required spare parts are
also provided with the basic system, including spare membranes, electrolyte, o-rings, and any
special hardware.
Note that standard 25 foot sensor cables for both ClO
2
and optional pH sensors can be cut to a
shorter length. Cutting the cables will not affect performance, and elimination of extra cable can
sometimes eliminate electrical noise pickup through the cables.
