Selecting a wavelength
Selecting the correct wavelength is important to get the
best data and can easily be determined using one of two
different methods. There is no incorrect wavelength, just
some which are more informative than others. Lab
experiments
wavelength to use. If your experiment does not, follow
one of these methods for best results:
 Knowing that the color we see solutions is based on
the color reflected from them (and not absorbed):
Choose a color you know will be absorbed. For
example, if the solution is red try the blue LED option.
 Once the sensor is connected and the NeuLog
software is open (follow one of the guides below for
more instruction) click the "Module setup" button in
the module box and try the different LED color options
to determine which has the highest absorbance (it will
appear in real time on the sensor's module box).
Select the color which has the highest absorbance
reading.
