1220 - Wireless Colorimeter and Turbidity Sensor

The Smart Wireless Colorimeter and Turbidity Sensor can be used to investigate a range of diverse scientific experiments:

• Rates of chemical reactions: determination of the rate and order 
• Finding the value of an unknown concentration by the Lambert-Beer Law
• Investigations with enzymes: effects of temperature pH, inhibitors, enzyme kinetics 
• Quantitative determination of biological molecules – sugars, protein, vitamins 
• Quantitative determination of inorganic ions – nitrate, phosphate, chlorine, bromine 
• Population growth of micro-organisms 
• Cleanliness measurements of water
• Dosing biomass growth
• Algae bloom
• Phytoplankton development
• Sediment erosion
• Mud and silk deposition post storm activity

Example Data:

1. Demonstrating Turbidity Development: Sodium thiosulphate and hydrochloric acid, monitored using the turbidity function. The reaction produces a deposit that develops in time.   

2. Demonstrating Reaction Rates: Sodium thiosulphate (variable) and hydrochloric acid Reaction, monitored using the colorimeter. 

3. Storm surge turbidity measured days following the event.
