Preliminary Examination
General Description
The C 221 portable microprocessor analyzer measures the
percent light transmittance of honey compared to analytical
reagent grade glycerol. The transmittance value allows
identification of the honey Pfund grade. The instrument
directly displays the measurement result expressed in mm
Pfund.
Measurements are made using matched square optical
cuvets having a 10 mm light path.
Display codes aid the user in routine operations.
The meters have an auto-shut off feature that will turn the
instrument off after 10 minutes of non-use.

Sampling in progress. This flashing
prompt appears each time the meter is
performing a measurement.
The microprocessor is adjusting the light
level, indicated by a scrolling "SIP".
This indicates that the meter has been
calibrated and measurement can be
performed.
The blinking "LOBAT" indicates that the
battery voltage is getting low and the
batteries need to be replaced.
This indicates that the meter is in a ready
state and zeroing can be performed.
This indicates that the batteries are dead

ERROR MESSAGES
a) on zero reading:
This indicates that the zeroing procedure
failed due to a low signal-to-noise ratio. In
this case press CAL again.
Honey color varies naturally in a wide range of tonalities,
ranging from light yellow to amber, dark amber and black in
extreme cases; sometimes green or red hues may also occur.
Color of untreated honey depends on botanical origin: for this
reason color is very important for definition and commercial
classification of monofloral honeys. Honey darkens with ageing,
and other changes in color may result from beekeeper’s
interventions and from the different ways of conservation (e.g.:
use of old honeycombs, contact with metals, high temperatures,
exposition to light, etc.).
The primary characteristic for commercial honey classification is
color. Color classes are expressed in millimeters (mm) Pfund
grades, compared to an analytical grade Glycerol Standard
Reference.
Table 1 reports the USDA classification for honey samples and
the related mm Pfund values.
Table 2 shows the color of different monofloral honeys: data are
obtained from a statistical set of honey samples. The table
reports for each type of honey: average value of color, standard
deviation, and the minimum and maximum values measured.
