- Handheld pocket refractometer for measuring the a of moisture in honey between 12.0 to 30.0%, with a temperature range between 10.0 to 40.0 degrees C.
- Automatic temperature compensation (ATC) for immediate and accurate calibration readings, regardless of ambient temperature.
- LED-illuminated digital display, with an external light interference (ELI) feature to alert of outside light interference.
- Rectangular palm-sized shape (109 x 55 x 31mm), with prism housed in circular sample well.
- Durable, acrylonitrile butadiene styrene (ABS) resin body for use with salty samples; Ingress-Protection (IP)-65 rated for protection against dust and water jets.
The Atago 4422 PAL-22S is a handheld, portable, water-resistant
honey refractometer with a honey moisture scale that measures in
the 12.0 to 30.0% range, has automatic temperature compensation
(ATC), an LED display with external light interference (ELI)
technology, and an acrylonitrile butadiene styrene (ABS) resin
Ingress-Protection (IP-65)-rated body. Handheld refractometers,
also known as sugar meters, concentration meters, or Brix meters,
are commonly used in the culinary, food and beverage,
ceutical, educational, geological, , and ecological
industries, and for water-testing applications.
This refractometer is housed in an ABS resin body for use with
honey samples. The 4422 PAL-22S features ATC for immediate,
accurate readings, with an ambient temperature range of 10 to 40
degrees C. The unit is factory-calibrated (calibration
certificate not included) and can be calibrated with tap water.
The metal sides of the sample well allow the sample temperature
to conform quickly and evenly to the prism temperature for
accurate measurements. The sloped shape eases sample pouring, and
helps avoid spills while taking measurements. The outer shell is
shaped for easy gripping, with raised grip dots on the back side
where the fingertips rest. The LED-illuminated digital display
with ELI technology helps provide accurate measurement near
windows or outdoors. ELI alerts the user that there is too much
light, such as direct sunlight, penetrating through the prism.
The unit displays both honey moisture and temperature within
three seconds, and comes with a protective plastic storage case
with a foam cut-out insert to cushion the instrument.

Refractometers are used to determine substance content in a
sample, to provide unit readings of substances including Brix,
salinity, and alcohol; to detect impurities, or to
measure components of samples such as industrial fluid.
Refractometers measure the refractive index of a substance, which
is its optical characteristic, and the number of dissolved
particles in it. The refractive index is the ratio of the speed
of light in empty space to the speed of light in a substance;
when light passes from one medium to another. Generally, a low
concentration sample has a larger angle of refraction than a high
concentration sample. For example, a straw placed in a
high-concentration substance appears more bent than when placed
in a low-concentration substance. Refractometers can work with
natural light, or with an external power source such as batteries
or electricity. They typically have either a digital or analog
reading display, though some units utilize both types. Some
analog-display refractometers can be used for both solids and
liquids. Digital-display refractometers are used exclusively for
liquids. Types of refractometers include handheld, benchtop, and
in-process. Handheld refractometers are elongated and
tele-shaped, or shorter and rectangular. Analog handheld
refractometer readings are obtained by looking through the
monocular eyepiece and viewing where the boundary line intersects
with the memory line. Digital handheld models provide a digital
readout. Benchtop refractometers typically measure with a higher
degree of accuracy than handheld units. In-process refractometers
are used for continuous process monitoring and data readouts, and
are generally fitted into a piping system for ongoing analysis.
Refractometers are used in a wide variety of applications in the
culinary, food and beverage, ceutical, educational,
geological, , ecological, and automotive industries, and
for water-testing applications.
