1 Description of the instrument
Your RQflex® plus 10 is a versatile, precise instrument. It is part of the
Reflectoquant® system with the components:
•
instrument RQflex® plus 10
• Reflectoquant®
tests
•
test- and batch-specific bar-code strip
According to the principle of reflectometry (remission photometry), diffuse reflected
light from the test strip or after transmission through a cell is measured. Just as in
classical photometry, the difference in intensity of emitted and reflected light
allows a quantitative determination of the concentration of specific analytes.

Up to five test methods, e. g. nitrate, pH value, can be stored simultaneously.
Test methods are loaded by means of the bar-code strip.
Bar-code scanner

All information necessary to run the instrument is communicated via the bar-code
strip. The bar code contains information for wavelength correction and for the
batch-specific calibration curve.
When the instrument is switched on, all elements of the display are shown for
about one second. In this time the instrument runs a self-test. Ensure that all
functions, especially the multifunctional digit display, are shown correctly.
