Digital touchscreen refractometers for laboratory or factory use.

Each RFM-T Series digital refractometer is fitted with a Peltier temperature control system, wide beam optics, a precision engineered flat prism surface for easy-cleaning, and a state-of-the-art 7” capacitive touchscreen which is bright and clear, durable, and simple to use.

RFM300-T Series

RFM330-T digital refractometer with 2 or 3-decimal place / 0-100 Brix (1.58 RI) touchscreen input and Peltier temperature control. Perfect for measurement and control in demanding food, beverage, chemical and industrial applications.

  • High definition touchscreen display.
  • Flat prism surface for easy-cleaning.
  • Wide beam scan for non-homogenous samples.
  • Supports FDA regulation 21 CFR Part 11.

RFM300-T Series refractometers are capable of measuring non-homogenous samples such as fruit juice with pulp, opaque chemical compounds and emulsions that are normally difficult to read with optical refractometers.

RFID swipe technology comes as standard, providing clearance and a log of operator and configuration functions – especially useful when being used in FDA-regulated environments operating in accordance with 21 CFR Part 11, or where good practice is adopted, e.g. as part of HACCP.

RFM900-T Series

The RFM900-T Series refractometers are high precision instruments for use within petrochemical, pharmaceutical, flavours and fragrance industries.

  • Easy clean prism.
  • Wide range – 1.30 to 1.70 RI.
  • Up to 6 decimal places RI.
  • Wide temperature range.
  • Peltier temperature control.
  • 7” High definition touchscreen.
  • Temperature stability checks.

Methods for petrochemical applications include ASTM D 1218, D 1747 and D 5006. Additionally, a method is included for ASTM D 2140 that requests external data input of viscosity, density and relative density.

RFM900-T Series refractometers are supplied with free software for your PC so that when connected to a network via Ethernet connection, the instrument can be remotely handed by an external service or support centre for diagnostics or even be used for training or installation qualification.
