Introduction & Background What is it?
A device to detect the colour and clarity of a uniform flowing water sample
How will it work?LEDs, a diffraction grating, a photodetector array and an on-board PC
Why do we need it?Demand from Aqua-culturists and Water Regulation Authorities for a cheap and easy to use device

Current Products Turbidity Meters (~$800s -
$1000s) Advantages
Cost Less than Spectrometers
Small and Portable Disadvantages
Cannot do color detection on samples
Usually implement detection by use of vials (not real-time analysis)

Current Products Mass Spectrometers
(~$100,000s) Advantages
High resolution detection of a sample’s color content
Very Accurate and Stable System
Disadvantages Not a real-time analysis Bulky and Not portable Very High Cost

Current Products Mini Spectrometers (~$2000s)
Advantages Cost Effective Solution to Mass
Spectrometers Compact Size Can be implemented to do real-
time analysis Disadvantages
Cost More than Turbidity Meters Lacks some resolution and
accuracy to mass spectrometers
