FEATURES

The Model WQS water quality system is intended for
the determination of pH, ORP, conductivity, tempera­ture, free chlorine or monochloramine, oxygen, turbidity,
and particle index in fresh water. The system com­bines user-specified instruments and sensors to create
a customized system for monitoring water quality.
Unlike systems from other manufacturers, the Model
WQS does not use expensive sample conditioning
systems or messy reagents.

Model WQS systems require less than 3 gph (183
mL/min) sample flow. There is little waste, which is
important in areas where water is scarce or a sewer is
not available.

Designed for quick startup and low maintenance

• No reagents — free chlorine and monochloramine
sensors are completely reagent-free

• Variopol quick disconnect sensors

• Prewired and plumbed

• Low sample flow; <3gph (183 mL/min)

APPLICATIONS

Rosemount Analytical recognizes that a “one size fits all” approach to water quality monitoring
does not provide the most efficient or economical solution to your needs. That is why
Rosemount Analytical offers a flexible approach that lets you choose the analyzers you want to
make the measurements you need. We offer platforms that range from basic analog output
instruments to transmitters with digital outputs powered by solar energy. Through our Emerson
Process Solutions Group we can provide wireless solutions and control systems that allow you
to look at each parameter from a central location.
