Colorimeter Sensor (SmartQ)

Colorimeter Sensor

The Colorimeter measures the amount of light penetrating a solution so can be used for investigations which result in a change in colour or opacity e.g. Beer’s law, enzyme kinetics and chemical rate of reaction experiments.

Warranty & Support

All our sensors are supplied with 5 years warranty and lifetime support.

Measuring Colorimetry

It has two ranges: Transmittance (%T) - the amount of light being received referenced to the light sent and Absorbance (Abs) - the amount of light absorbed by the solution.

The light source in the Colorimeter is a white LED which has the advantage of not heating the solution being studied. This white light passes through a cuvette that contains the sample solution, some light is absorbed so the amount received by the photodiode is of lower intensity. A snap-shut lid prevents stray light entering the unit from the environment.

Practical Teaching

The Colorimeter can be used to investigate a number of scientific experiments such as:

  • Reaction kinetics
  • Reaction kinetics of enzyme systems
  • Rate of reaction with Thiosulphate and acid catalyst
  • Beer Lamberts law (light absorbance vs. concentration)
  • Population growth of micro-organisms
  • Estimation of unknowns e.g. glucose concentration, manganese in paper clips
