METTLER TOLEDO has developed the PortableLab™ series of hand-held instruments: Despite their compact size, the Densito 30PX density meter, the Refracto 30GS (high-end) and the Refracto 30PX refractometers as well as the X-matePro pH/multimeter offer the features you would expect from a large bench-top instrument: You get a wide array of configuration possibilities for perfect adaptation to your application; you can execute measurements with a minimum number of keystrokes thanks to the straightforward and intuitive user interface and you can save measurement data for later transfer to a Personal Computer (Densito and Refracto even over an IrDA infrared interface) and printer.
