Refracto 30PX/30GS

Portable Refractometers

Measurement Cell with
Temperature Sensor

The 30PX and 30GS differ in their prism
and measurement cell. The 30PX uses a
glass prism held by a stainless steel
ring. With a sapphire prism held by a
gold-plated brass ring, the 30GS has the
broadest measurement range than any
other portable instrument.

Temperature Compensation

The refractive index of a sample depends
on temperature. During measurement,
Refracto determines the temperature and
then corrects the refractive index to a
standard temperature of 20°C or any
other temperature the user defines. Up to
10 user defined correction coefficients
can be stored which allows for quick
measurements of different sample types.

Handheld or Benchtop

Refracto 30PX/30GS is a handheld and
benchtop refractometer in one. The cell
can be immersed directly into the sample,
or place the Refractro 30PX/30GS on a
flat sur face and add a drop of sample into
the measurement cell. This flexibility
allows you to take accurate
measurements the way you need.

Data Management

Refracto 30PX/30GS allows you to save
1,100 results – including information such
as sample and instrument identification,
measurement unit, temperature correction
coefficient, date, and time. Data can be
transferred to a PC or printer at any time
using the infrared interface.

Reliable Results Within Seconds

Whether you are checking the sugar concentration
in beverages or the hydrocarbon content in motor
fuels, Refracto 30PX/30GS returns accurate
and precise results within seconds, displayed in the
measurement units needed.

Using the total reflection method combined with
precise temperature measurement and an elegant user
interface, Refracto 30PX/GS quickly and consistently
gives reliable results.
