Low Range Turbidimeter User Guide 6
2. PRODUCT DESCRIPTION
The AquaClear Turbidity System is used for continuous monitoring of low-range turbidity in drinking water
applications. The system also measures water temperature.
In the standard system configuration, data is reported through a local display and a scalable 4-20 milliamp
current output. Options include a second current output, up to 2 configurable relays and one of several digital
protocols for remote monitoring, calibration, configuration and diagnostics. All functions can be accessed
through a digital network with or without a local display interface.
The AquaClear Turbidity System uses a pre-calibrated optical detector mounted in a sample chamber
specifically designed to prepare water for low-range turbidity measurements. A collimated white light in the
chamber lid is used to illuminate particles suspended in the water.
The chamber removes bubbles from the water so that solid particles can be accurately detected. The
chamber lamp will provide collimated white light for up to two years and is easily changed from the top.
Because the chamber volume is only 135 milliliters, it takes a very small amount of Formazin to perform EPA
mandated calibrations.

Plug and Play Industrial Communications Adapters
The AquaClear Drinking Water Turbidity system is part of the DataStick family of products. The DataStick can
be used with any sensor head manufactured by Thermo Fisher Scientific and can communicate directly with
industrial computer systems using any of the communications adapters offered. The Thermo Scientific
AquaSensors AV38 local display is provided as standard equipment for the Turbidity System. It is however
not required and any number of turbidity systems can be digitally networked to a single computer interface.
Open protocol commands for calibration, configuration, diagnostics and measurement are available (consult
the desired communications manual).
