The PortableLab™ – Measure anywhere just like in the laboratory
METTLER TOLEDO of course offers portable density meters and refractometers:
The Refracto 30PX and 30GS are compact, easy-to-use refractometers. Depending on the application,
they can be operated either as bench-top or immersion refractometers.
The Densito 30PX is a real multi-talent as far as density measurement is concerned. Precise determina-
tions can be made in just a few seconds, and the result is displayed directly in the desired units.
Would you like to know more about the PortableLab instrument family, see the instruments in practi-
cal use or take a look at the operating instructions? We will gladly provide you with the information you
require and welcome you any time at our Internet address (www.PortableLab.com).
