Product description

Mettler Toledo Refracto 30GS portable refractometer

Refracto is a hand-held and a benchtop refractometer in one. You either place the instrument on a flat surface and add a drop of sample onto the measurement cell or immerse the cell directly into the sample.

Sapphire prism

Refracto determines refractive index using the total reflection method. The prism of the Refracto 30GS is made of sapphire and held by a ring of hard gold plated brass. 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. Refracto even measures dark samples correctly. You no longer need to rely on error-prone readings of dark/bright transitions as with optical instruments.

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. To make quick measurements of different types of samples, you can easily switch between up to 10 user defined correction coefficients.

Transfer your data whenever you want

You are free to transfer the data (together with an instrument identification) to a PC or printer any time using the IR interface. For this purpose an infrared / RS232 converter (51325006) is required. Appropriate PC software comes with the instrument.
