Refractometers are optical devices used to measure the refractive index of substances. They can measure properties like salinity, concentration, specific gravity, and blood proteins of liquids. Digital refractometers have a range of scales for various applications and are precise, while handheld refractometers allow for convenient and rapid measurement of samples. Refractometers work by measuring how much a substance bends light passing through it, using the shadow created to determine the refractive index and sample properties. They are commonly used in industries like winemaking, food processing, and aquariums.

Weiber manufacture an extensive range of digital and handheld refractometers to measure the index of refraction
of substances. These refractometers include Digital Brix refractometer, Abbe refractometer, Gem refractometer,
Digital Coolant and Battery Refractometer etc. Refractometers are equipments that are used to measure the index
of refraction of substances. These can be extensively used to measure the total plasma protein in blood sample, to
measure the specific gravity in urine and these are also used in marine aquarium to measure the salinity of water.
Refractometer is an optical device, which measures the Refractive Index of a substance which can be liquid, gases
and translucent solids such as gemstones. Refractive index is a physical property that is characteristics of a pure
compound it is a measure as to how much light is bent while passing/travelling through a gas, solid or solution. The
amount of bending of light is used as a method of determining the properties of substances. This bending of light by
the water is called Refraction. Light bends to different degrees as it passes through different substances. When the
device is used to test liquids, it typically measures the salinity, fluid concentration, specific gravity, and blood
proteins. The lenses and prisms inside the Refractometer create a shadow line inside it that can then be viewed
through a magnifying eye piece to note the measurement. Refractometer has a built in Thermometer and
circulating water to control their Temperature and also equipped with adjustments to eliminate the effects of
Dispersion.
Refractometer are commonly used in wine making in order to measure the grapes’ or fruits’ sugar content and
assess their ripeness or used in chemical processing industries such as
Sugar refining industries
Making alcohol the percentage of alcohol is determined by its Refractive Index.
ii) To determine the protein concentration in animal blood samples
iii) To determine the salinity of a salt- water aquarium.
iv) To determine the solute concentration in a solution.
v) For checking the Refractive Index of solids especially gemstones and other transparent minerals.

DIGITAL REFRACTOMETERS
The Digital Refractometers have an extensive range of scale
types for use in a wide variety of applications. The equipment is
sturdy and has a long battery life. These digital automotive
refratometers use latest and precise optical cells. These coolant
and battery refractomers use digital picture processing technique
and accurate temperature damages. Advanced microprocessor is
centre of the digital coolant and battery refractometer which
analyze the ethylene and propylene glycol and battery charge
conditions with precisions displays as three and half figures
number liquid crystal displayer.
HAND HELD REFRACTOMETERS
These instruments facilitate convenient and rapid measurement of
concentration in a number of liquid and semi solid samples. They
are also useful for determining salinity, blood levels of proteins,
specific gravity etc. Hand-held clinical refractometer with a brighter
than usual display. The prism house of the ACQ-1 is made of metal,
the temperature of hot or cool samples quickly conforms to the
temperature of the prism. A carrying pouch is included. Use it to
measure salt concentration in a given liquid.
