Functional Principle - Henry Schein OneStepPlus User Manual

User manual
The stick is illuminated with an LED and a detector registers the intensity of
light reflected by the test stick at three different wavelengths. Using an
internal calibration, the results are calculated from the reflection values.
Whenever samples are strongly alkaline, a density correction is
automatically conducted.
