Measuring absorbances
Besides measuring concentrations using a selected method,
the unit is also capable of measuring absorbances. For this you
call up the desired wavelength by entering the corresponding
method number or by choosing from the method-selection list.
Measuring range: -2600 mAbs to +2600 mAbs
Method No.

The display shows e.g.:
Always zero the colorimeter using a filled cell
(e.g. with DI water).
The display shows e.g.:
Then measure the sample.
The display shows e.g.:
100 mAbs = 0.100 A (absorbance units)
Tip
Reaction times for your own measurements in the absorbance
mode can be more easily observed by using the user-countdown
function (see the following section 2.6, “User countdown”).
