The RFM340-T digital refractometer has a 3-decimal place / 0-100 Brix (1.58 RI) touchscreen input and Peltier temperature control. This refractometer is perfect for measurement and control in demanding food beverage chemical and industrial applications. They are designed specifically for these harsh environments and are extremely high-quality instruments. It incorporates wide beam optics to make it capable of measuring non-homogenous samples like fruit juice with pulp opaque chemical compounds and emulsions that are typically difficult to read with optical refractometers.

It includes a durable membrane made from chemical and scratch resistant polyester to offer a more tactile approach allowing users to navigate menus at the touch of a button. This refractometer is equipped with large clear buttons and a 4-inch-high resolution screen that helps facilitate operation in factory environments and combined with the latest GUI helps operators manoeuvre through menus. There are on-screen prompts that support simple operations such as method loading calibration and routine maintenance that can be carried out by anyone.

The key features of this refractometer include:

  • Tactile & robust keypad
  • Flat prism surface for easy-cleaning
  • Wide beam scan for non-homogenous samples
  • Three decimal place Brix precision* (6 d.p. RI)

The refractometer case is designed so that spills are dealt with by the slope shape of the case or by the PEEK spill barrier that surrounds the shallow easy-clean stainless steel prism dish.
