Merck RQflex 10 - Display and operation keys

Description of the instrument
Your RQflex 10 is a versatile, precise instrument. It is part of the
Reflectoquant® system with the components:
• Instrument RQflex 10
• Reflectoquant® strips
• Test- and batch-specific bar-code strip
According to the principle of reflectometry (remission photometry), reflected
light from the strip 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 analytical methods, e.g. nitrate, pH value, can be stored simulta-
n e o u s l y. Methods are loaded by means of the bar-code strip.
Bar-code scanner 6
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.
