Hi Roger,
I will not comment on the two mentioned instruments.
But in general it is true that a colorimeter has advantages over a spectrometer
when very low signals need to be measured.
Reasons are e.g.
a) sensitivity: the spectro divides the few photons into 30+ bands, the
colorimeter into 3-7
b) noise: a contact measurement warms up the instrument which creates noise
which makes the readings of very low signals less reliable
Does this make sense to you?
Of course there are spectrometers available which do not suffer from the
disadvantages as actions have been taken to overcome them.
Best regards
Claas
