Introduction
The AQUANAL®-plus Spectro turbidity is designed as a compact, easy to use instrument to determine turbidity fast and accurate. A light emitting diode (LED) is used as a light source with a photodetector positioned to detect light scattered by a sample at 90°C to the incident beam. The LED is characterised by maximum long-term stability and monochromatic light emission with minimum power input. The sample chamber (the most critical part of any photometer) is fully sealed, so no water can penetrate into the electronic components. The size of the sample chamber ensures easy cleaning of the light entry surfaces. The AQUANAL®-plus Spectro turbidity may be used as test equipment with software-based calibration adjustment facilities. Battery operation makes the unit suitable for both mobile use and laboratory applications. The AQUANAL®-plus Spectro turbidity is supplied as a fully functional unit complete with accessories and calibration standards in a handy case.

Ratio and Non-Ratio Instruments
Ratio Turbidimeters look at light scatter utilizing more than just the 90° sensor. The quotient of the relationship of the sensors is the resultant NTU value.

Light Scatter Characteristics
Small particles
Formazine particles 1.75 - 20 microns
Styrene-diphenylbenzene suspension 0.2 - 0.8 microns
Conclusion
Different standards, because of their physical properties (shape size and refractive index) do not interact with nepheolometric instruments in the same way all the time. |
