3. Non-contact free-fall concept
Water passes through the AquaScat without touching the optics:
No window fouling. Hence, the measured values are not falsified and there is no drift.
Very Low to very high turbidity values can be measured with no contamination of the optics
Dissolved metals like iron or manganese do not contaminate the optics
Extremely low maintenance is the result
Measuring light passes through the entire sample beam:
There is no selection of the sample at the surface. The entire water beam is measured and hence, the result is representative.

5. Re-calibration with secondary standard (High stability optical glass)
WTMA: Automatic calibration check
Re-calibration with secondary
standard (High stability optical glass)
Precise re-calibration is possible without the use of Formazine
Allows a stable measurement over a long time period
Allows a fully automatic operation
Purchase and storage of Formazine is not needed

8. Low levels of stray light
The design of the AquaScat in combination with
high quality optical components minimizes the
quantity of stray light inside the instrument:

9. The control unit of all AquaScat is a colour touch screen:
Values, graphs, alarm and status messages can be selected by the operator.
An internal data logger allows the recall of measured data for the last 32 days
Password protection avoids unauthorized access
Various means of communication including an integrated web server

10. The maintenance work is very low
Cost of ownership
In addition to its daily dependability, the product design was focused on long useable life and low maintenance costs:
The maintenance work is very low
The cost for consumables during 10 years of operation are at AUD 150

11. Turbidity measurement application The installation is simple
An optional de-aeration system can be installed if required.
2 Analogue outputs can transfer two measuring ranges to the PLC
