Maple Syrup Digital Grader
QUICK REFERENCE GUIDE
Tips for an Accurate
Measurement
When taking measurements, the outside of the cuvette
must be dry and free of syrup, ngerprints, oil, or dirt.
Wipe it thoroughly with a lint-free cloth prior to insertion.
Make sure cuvettes and syringes are completely
dry before using. Excess water will leave streaks in
the syrup sample which may aect results.
Dispense or pour the sample slowly. When transferring
the syrup into the cuvette, be careful not to generate
bubbles as they may cause inaccurate readings.
It is important that the sample does not contain debris.
After the reading it is important to immediately discard the
sample, otherwise the glass may become permanently stained.
