B+S RFM300 series laboratory digital refractometer

The RFM300 series refractometer is customer-oriented and combines over 100 years of design and manufacturing experience. The RFM300 series refractometer has a wide measurement range. For the Peltier temperature control of flat and easy to clean prisms, it can quickly stabilize the temperature of the sample, allowing for fast and reliable readings on any scale (including ° Brix, refractive index (RI), or up to 100 user-defined scales).

Whether equipped with a high-resolution 7-inch touchscreen (RFM300-T) or a more tactile keyboard (RFM300-M), the user interface menu of this instrument is simple and easy to use, bringing a brand new interface to the RFM300 series instruments, which is eye-catching.

The large sampling area on the prism surface not only allows for the measurement of homogeneous liquids such as juice, soda water, sauce, and edible oil, but also enables the measurement of difficult to read sample data such as fruit pulp and industrial resin.

Intelligent software ensures rapid response to prism temperature changes, while SMART temperature stability checks ensure that results are only displayed when the sample is stable. The method system allows for quick configuration of instrument settings and provides limit checks and product specific corrections for stored data, such as the citric acid content of orange juice or the daily offset of coffee solids. The instrument memory can store over 8000 readings, and the screen menu can be displayed in multiple languages.

This instrument has two formats, and the commonly used one is the Brix RFM340 refractometer with 3 decimal places. After the improvement of the dynamic thermal control system, the measurement performance has been improved between 0~30 ° Brix, thereby reducing potential measurement errors within the critical range of finished products such as juice and soda water mentioned above. By improving the low-end performance of the scale, users can dilute the syrup to the absolute minimum value without violating the minimum syrup value regulations in production.

The sucrose specific gravity scale is also common in this series. These scales can be used to represent the relative density of pure sucrose solutions, and when used in conjunction with product offsets within the method system, the finished beverage can be expressed as equivalent specific gravity.

In this way, contract packaging companies for beverage products can use refractometers on site, with density ° Brix or specific gravity as the specified analysis method, while retaining all the measurement advantages of refractometers. The dual display function allows the original Brix or RI to be displayed together with the equivalent sucrose density results.

Other new features of the RFM300 series have now become standard, including RFID user licensing, electronic signatures, and audit tracking for use in FDA regulated environments (21 CFR Part 11), and additional functionality such as backup and cloning, as well as printing to secure PDFs, is available through a new USB interface.
