LiquiPhysics™ Excellence RM Digital Benchtop Refractometers allow users to determine the refractive index, BRIX, HFCS, or user-defined concentrations of a wide variety of liquids quickly and accurately.

• Determine refractive index
• Measures the total reflection of light
• Sophisticated and intuitive software
• Built-in Peltier temperature control

A high-resolution optical sensor measures the total reflection of light from the LED after it strikes the sample and the RM reports the results with accuracy up to five decimal places.

Built-in Peltier temperature control provides both reliable temperature stability and rapid heating/cooling rates. The inert sapphire prism facilitates measurement of thin, highly volatile, dark, or viscous liquids. The removable top section provides ease of cleaning with simple tap water without the need for tools. The RM’s sophisticated yet intuitive software enables you to easily perform complex statistical evaluation methods so you have full confidence in your data. One ClickTM shortcuts streamline workflows by allowing users to initiate the most frequent methods with a single tap of an icon on the color touchscreen. Elegant ergonomic design, customizable user settings, and multilingual support make the RM family of instruments appealing and easy to use by a wide variety of operators.

Plug-and-play connection of accessories such as the printer, barcode scanner, LogStraight™ biometric fingerprint reader, and ErgoSens™ infrared sensor for hands-free operation is quick and easy. Assisted sample loading and clearing are possible through the addition of FillPal™ and DryPal™ units.

The available EQPac (Equipment Qualification Package) delivers peace of mind to those working in regulated environments by providing comprehensive and detailed qualification guidance (IQ/OQ/PQ).
Finally, METTLER TOLEDO Certified Combined Density and Refractive Index Standards reduce risk, uncertainty, and error-prone sample transfer. The standards arrive complete with certificates including an easy-to-scan barcode containing all information necessary for calibration. Barcodes save valuable time, reduce data entry error, and improve traceability.
