Digital Refractometer RFM330-M Switch Membrane Bellingham + Stanley 19-35

PART NO: X-19-35

The RFM330-M digital refractometer has a 2-decimal place/0-100 Brix (1.58 RI) touchscreen input along with Peltier temperature control and keypad. It is perfect for measurement and control in demanding food beverage chemical and industrial applications. This refractometer is designed for use in these harsh environments and is high quality. 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 features include:

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

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.
