The VEE GEE CTX-1 is a handheld, portable, water-resistant
antifreeze and battery charge level refractometer that measures
the freezing point of propylene glycol in the -50.0 to 0.0
degrees C range, freezing point of ethylene glycol in the -50.0
to 0.0 degrees C range, and the specific gravity (SG) of battery
in the 1.10 to 1.40 range, has automatic temperature
compensation (ATC), and a durable metal body with rubber grip.
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 a durable metal body. The VEE GEE
CTX-1 features ATC for immediate, accurate readings, with an
ambient temperature of 10 to 30 degrees C. The unit is
factory-calibrated and can be calibrated with distilled water.
Calibration can be controlled and adjusted with a tool-free
calibration ring and a set screw. The outer shell is rubber
coated with dimpled grip for easy gripping and the rubber coating
guards against hand heat for accurate measurements. A non-roll
stand prevents the unit from rolling when placed on a flat
surface such as a table or bench top. The optical glass prism is
ed in an all-metal housing composed of copper alloy with a
nickel-chrome coating for quick temperature equilibrium between
the sample and the prism. The analog Brix scale features a
bright, high-contrast display for clear visibility of the
boundary and memory lines intersection. Instantaneous sample
readings illuminated by ambient light are viewed through a
monocular, focusable, cushioned eyepiece. The unit comes with a
zippered vinyl carrying case, a plastic transfer pipet and an
instruction manual.

H is height, the vertical distance from the lowest to highest
point; W is width, the horizontal distance from left to right; D
is depth, the horizontal distance from front to back.
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.
