Additional Information: |
The operator can choose to have either uncompensated measurements or values that have been compensated for extrinsic effects. When using the compensated modes, the conductivity and pH values will be corrected for temperature. Dissolved oxygen readings are corrected for temperature, salinity, and atmospheric pressure.
All of these parameters, except atmospheric pressure, are measured with a single compact water quality probe which is equipped with standard lengths of cable. This allows remote multiparameter water quality measurements to be taken, with out the need to draw a sample.
The standard handheld multi-parameter
water quality measurment system comes with:

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.
