NeuLog colorimeter logger sensor NUL-219
The colorimeter sensor can be used for any science
experiment where liquid samples of different colors and
concentrations are utilized such as in the fields of
Chemistry,
Environmental Science, Physics, or even just to study the
behavior of light waves.
Colorimeters are used to determine absorbance or
transmittance of given wavelengths (generally red,
green, and blue) in a liquid solution. Absorbance and
transmittance are directly related to the concentration
of known solutes in the solution which is calculated using
the Beer-Lambert law. One parameter can be
calculated from the other.
The sensor comes pre-calibrated so you can start
experimentation right out of the box using this guide.
Hundreds of possible experiments that can be
performed with the NUL-219 sensor are: Analyzing
chemical reactions, studying Beer's Law, water quality
testing, monitoring of ecological systems, study of
photosynthesis, studying light waves. The colorimeter
could take the place of a spectrophotometer in many
experiments.
The NeuLog colorimeter sensor's measurement units
are:
 % Transmittance: The amount of light that passes
through a sample.
 Absorbance: The amount of light which is absorbed by
a sample.
