• Portable Refractometer
Refracto 30PX (left) and Refracto 30GS (right) are compact,
easy-to-use refractometers for measurements in laboratory
and production environments. Depending on the application,
these instruments can be used in two ways: Either put it
on a flat surface and place a drop of sample onto the measurement
cell, or immerse the sensor directly into the fluid. As
soon as you press the measurement key, the result is displayed
in the desired units on the backlit LC-Display. You no longer
need to rely on error-prone readings of dark/bright transitions
as with optical instruments. Refracto even measures dark
samples correctly. Because the refractive index is temperature
dependent, Refracto also automatically compensates the result.
30PX and Refracto 30 GS: What is the difference?
The Refracto 30PX (left) has a measuring cell made of optical
glass, whereas the Refracto 30GS (right) has a measuring
cell made of sapphire. Sapphire has a higher refractive
index and a better thermal conductivity than glass. For
this reason the Refracto 30GS has an extended measuring
range and registers the sample temperature more quickly.
