9. If the sensor is connected to the data logger, check the output of the sensor in the data
display in
LoggerNet
,
RTDAQ
, or
PC400
to make sure it is making reasonable
measurements.
5. Overview
The heart of the ClariVUE 10 is a near-infrared (NIR) laser and a photodiode for detecting the
intensity of light scattered from suspended particles in water. The detector is positioned at 90
degrees to the emitter to measure the side-scatter energy. The ClariVUE 10 has two
measurement ranges. The low range is from 0-400 TU and uses a transfer function to convert mV
readings to turbidity units based on 4 calibration points in this range: 0, 20, 100, and 400 TU. The
high range is from 401 to 4000 TU. The high range transfer function converts millivolt to turbidity
units using seven calibration points across the full measurement range: 0, 20, 100, 400, 1000,
2500, and 4000 TU.
Turbidity sensors are used for a wide variety of monitoring tasks in riverine, oceanic, laboratory,
and industrial settings. They can be integrated with water-quality monitoring systems,
conductivity, temperature, and depth sensors (CTDs), laboratory instrumentation, and sediment-
transport monitors.
Applications include:
l
Compliance with permits, water-quality guidelines, and regulations
l
Determination of transport and fate of particles and associated contaminants in aquatic
systems
l
Conservation, protection, and restoration of surface waters
l
Assessing the effects of land-use management on water quality
l
Monitoring waterside construction, mining, and dredging operations
l
Characterization of wastewater and energy-production effluents
Features:
l
Fitted with wet-pluggable connector—multiple mating cable length options available
l
Accurate and rugged
l
Compatible with any SDI-12 data logger/controller including Campbell Scientific GRANITE-
series, CR6, CR3000, CR1000X, CR800-series, CR300-series, and CR1000
