MA871/MA872/MA873/MA881
Digital Refractometers for Brix, Fructose, Glucose
and Invert Sugar Measurements
The digital refractometers
are optical instruments that
employ the measurement of
refractive index to determine
the % Brix of sugar (MA871), % Fruc-
tose (MA872), % Glucose (MA873) and
% Invert Sugar (MA881) in aqueous
solutions.

The method is both simple and quick.


Samples are measured after a simple
user calibration with deionized or
distilled water. Within seconds the
instruments measure the refractive index of the
sample and convert it to % Brix or % by weight concentra-
tion units.

The digital refractometers eliminate the uncertainity


associated with mechanical refractometers and are easily
portable for measurements in the field.
The measurement technique and temperature
Key features include: compensation employ methodology recommended in
• Dual-level LCD the ICUMSA Methods Book (Internationally recognized
• Automatic Temperature Compensation (ATC) body for Sugar Analysis). Temperature (in °C or °F) is
• Easy setup and storage displayed simultaneously with the measurement on the
• Battery operation with Low Power indicator (BEPS) large dual level display along with icons for Low Power and
• Automatically turns off after 3 minutes of non-use other helpful message codes.

Measuring pH in meat
Using MW102 PRO+ pH portable meter
with a MA920B/1 pH electrode
The pH changes occurring in a carcass
during the first 24 hours after slaughter are
important for the quality of the final meat
or meat products. Protein denaturation will
occur if pH falls to too low a level or if a
relatively low pH sets in at a time after
slaughter where the carcass temperature is
still high. This will result in meat with poor
water holding capacity and in extreme cases
in meat that is PSE.

Calibrate the pH meter using pH 7 and pH 4


standardization buffers.

1. Cut meat sample into small pieces.

2. Weight approximatley 10 grams into a blender cup.


Run duplicates on each sample.

3. Add 100 ml of distilled deionized water and blend


for 30 seconds on high speed.

4. Transfer sample to a beaker. Read the pH as soon


as possible.

5. By pressing the HOLD key you can activate the


hold function. The measured value is frozen on the
display and the “HOLD” tag lights up. Release “HOLD”
by pressing HOLD key again.

6. Blender cups, beakers and stir bars can be rinsed


in distilled water between samples. The pH electrode
should be rinsed with distilled water between each
sample and periodically rinsed with acetone from a
squeeze bottle to remove fat buildup.
