Global Water’s WQ730 Turbidity Sensor is a highly accurate submersible instrument for in situ environmental or process monitoring. The sensor is ideal for a variety of applications, including river monitoring, stream measurement, reservoir water quality testing, groundwater testing, water and wastewater treatment, effluent and industrial control, and more.
|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 turbidity meter can be used for enivronmental or process sites that do not require permanent monitoring. The turbidity meter will display readings directly in either nephelometric turbidity units (NTU) or parts per million (PPM). The turbidity meter also includes an automatic shutoff feature to conserve battery power.|

|How it Works|
|In accordance with USEPA Method 180.1 for turbidity measurement, the WQ730 is a 90 degree scatter nephelometer. The sensor directs a focused beam into the subject 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 uses a second light detector to correct for light intensity variations, color changes, and minor lens fouling.
For environmental monitoring, simply place the sensor directly in the water and position it where the turbidity is to be monitored. For process monitoring, you can place the sensor into a low-pressure pipe for online monitoring using a standard 1.5" compression coupler.
|Record, Control, and Display|
|For handheld turbidity monitoring, the WQ770-B Turbidity Meter combines the WQ730 with a digital display that reads in either NTU or ppm. You can add recording capabilities to the WQ730 with the GL500 Datalogger, and you can use the sensor to control external devices with the PC300 Controller.|
