WQ770 Turbidity Meter

Turbidity Sensor
Global Water's Turbidity Sensor is a highly accurate submersible instrument for in-situ environmental or
process monitoring. Applications include: water quality testing and management, river monitoring,
stream measurement, reservoir water quality testing, groundwater testing, water and wastewater treatment,
and effluent and industrial control.
In accordance with USEPA Method 180.1 for turbidity measurement, the Turbidity Sensor is a 90 degree
scatter nephelometer. The sensor directs a focused beam into the monitored water. The light
beam reflects off particles in the water, and the resultant light intensity is measured by a photodetector
positioned at 90 degrees to the light beam. The detected light intensity is directly proportional to the
turbidity of the water. The turbidity sensor utilizes a second light detector to correct for light intensity
variations, color changes, and minor lens fouling.
Turbidity Meter
The Global Water Turbidity Meter combines the turbidity sensor (described above) with a handheld meter that
has a six digit LED screen, 4-button control panel, and an internal 9V battery. The handheld portable
water meter can be used for enivronmental or process sites that do not require permanent monitoring. The
meter will display readings directly in either nephelometric turbidity units (NTU) or parts per million (PPM). The
meter also includes an automatic shutoff feature to conserve battery power.
Turbidity Sensor Cleaning and Use
To maintain accurate readings with your turbidity sensors the lenses should be cleaned a minimum of
once per week. Depending on the monitoring site, the turbidity sensor's lenses may need to be
cleaned as much as once per day. The turbidity sensor has been designed for harsh field
conditions and uses the latest manufacturing design technology, however in applications where
constant monitoring is needed, Global Water recommends that the turbidity sensor should not be
kept submerged for more than one month at a time.
