Products 2 Description


  • Inert sapphire prism facilitates measurement of thin, highly volatile, dark, or viscous liquids
  • Removable top section provides ease of cleaning with simple tap water without the need for tools
  • Plug-and-play connection of accessories such as the printer, barcode scanner, LogStraight™ biometric fingerprint reader, and ErgoSens™ infrared sensor for hands-free operation
  • Assisted sample loading and clearing are possible through the addition of FillPal™ and DryPal™ units
  • Optional EQPac (Equipment Qualification Package) provides comprehensive, detailed qualification guidance (IQ/OQ/PQ) to those working in regulated environments

Expand Your Scope of Measurement
  • LiquiPhysics™ allows you to add parameters such as pH, color, and density/specific gravity to your refractive index readings
  • Simply connect a compatible SevenCompact™ pH or conductivity meter, colorimeter, or density cell to the RM module and define the method
  • Optional LabX™ LiquiPhysics™ Express software captures and manages all of these data points under a single platform
  • LabX™ also fully supports your CFR 21.11 requirements, provides user management, audit trail, flexible data export options, and fully customized reports
Reliable Standards
  • Mettler Toledo Certified Combined Density and Refractive Index Standards reduce risk, uncertainty, and error-prone sample transfer Standards come complete with certificates including an easy-to-scan barcode containing all information necessary for calibration
  • Barcodes save you valuable time, reduce data entry error, and improve traceability
