Whether you are checking the sugar concentration in beverages or the hydrocarbon content in motor fuels, Refracto 30PX and 30GS return 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.

• 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: 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 surface and add a drop of sample into the measurement cell. This flexibility allows you to take accurate measurements the way you need.
• Data management: allows you to save 1100 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.
