| A
refractometer is an optical instrument made of high quality
aluminum is used to measure the concentration or refractive
index of liquids. The RHB-10ATC, is specially designed to
work with sugar-related liquids such as low sugar fruits and
vegetables juices, Reamsian Bodily Fluids (per the Reams Biological
Theory of Ionization), Maple Sap or for synthetic or semi-synthetic
coolants, soft drinks and wine (for machining and grinding
coolants, please consult the Technical Data Sheet for appropriate
concentration of fluid). It
can help the user monitor the specific percentage of sugar
concentration in food and beverages, and is especially practical
for people involved with food harvesting, processing and packaging.
This
model is designed to give HIGHLY accurate readings with
0.10 Brix divisions (accuracy is +/- 0.10 Brix). This unit
is TWICE as accurate as 0-32% models!All RHB models use
ambient light which means battery or power source is
not required. Models with the ATC suffix are equipped with
Automatic Temperature Compensation for accurate measurements
without recalibration after shifts in ambient working temperature
(for field use). Against bright external light, the user
looks through the eyepiece of the Brix Refractometer to
see the reticle scale. The Brix Concentration (in percentage
units) is the mark on the scale where the light and dark
boundaries meet, with one to two drops of liquid specimen
spread across the refractometer's prism glass surface.
With
the Brix Refractometer RHB-10ATC, you can easily check the
ripeness of fruits in the field, or test the concentration
of sugar in food and beverages to ensure product quality.
Definitely easy to use and calibrate, this accurate optical
device has a durable, lightweight body with a comfortable
eyepiece and non-slip rubber grip. It also comes with its
own calibrating mini-screw driver and pipette as accessories.

Operating
Operation:
- Aim
the front end of the refractometer to the direction
of bright light and adjust the eyepiece (manual focus
adjustment) until the reticle scale can be clearly seen.
- Adjustment
of null (also called calibration): Open the daylight
plate. Place one or two drops of distilled water or
R.O water on the prism. Close the daylight plate and
press it lightly so the water spreads across the entire
surface of the prism without air bubbles or dry spots.
Allow the sample to remain on the prism for approximately
30 seconds. Then adjust the calibration screw to make
the light and dark boundary coincide with the null line.
Adjustment of refractometer should be made under the
condition of 20°C (68°F) environmental temperature.
When the working temperature of the room or environment
(not the sample) changes by more than 5°F, recalibration
of the refractometer is recommended to maintain accuracy.
The refractometer should also be adjusted to null before
storage.
- Open
the daylight plate and clean the surface of the prism
with soft cotton cloth. Drop 2-3 drops of solution to
be measured. Close the daylight plate. Press it lightly
so the water spreads across the entire surface of the
prism without air bubbles or dry spots. Allow the specimen
to remain on the prism for approximately 30 seconds,
and then read the corresponding light/dark boundary.
The reading is the Brix value of the measured solution.
- After
measurement, clean away the measured solution on the
surface of the prism and daylight plate with moist cotton
cloth. After drying, it should be stored properly.
Maintenance:
- Recalibrate
occasionally to ensure and maintain the testing accuracy.
- Adjustment
of null: Liquid and specimen should be under the same
temperature. If the temperature varies greatly, the
null point should be adjusted once every 30 minutes.
- Do
not use water to wash the refractometer after use to
prevent moisture from entering the instrument.
- As
it is a specialized precision optical instrument, the
refractometer should be handled gently and taken good
care of. Don't touch and scratch the optical surfaces.
It should be kept in a dry environment with clean and
non-corrosive air, to prevent the surface from turning
moldy and foggy. Please use the protective carrying
case to avoid strong shocks during transportation.
- If
the consumers use the instrument in accordance with
the method of usage specified, it can be guaranteed
that the instrument will be operational for quite a
period of time, with its optical performance unchanged.
