The RFM950 Automatic Digital Refractometer is a touchscreen laboratory refractometer for measuring the refractive index of transparent and semi-transparent liquids and determining Brix values of sugar solutions. It provides 0.00001 nD resolution, 0–100% Brix measurement, approximately 2-second reading time, automatic temperature compensation for Brix, 1024-result memory and password-protected calibration.

3. Detailed Product Description

Product Overview

The Labmart RFM950 Automatic Digital Refractometer is designed for automated measurement of refractive index (nD) in transparent and semi-transparent liquids. It can also measure Brix (BX) of sugar solutions and automatically correct the effect of temperature on the Brix result.

The instrument combines a touchscreen interface, automatic measuring system and easy-clean prism for routine laboratory operation. According to the supplied catalogue, the RFM950 provides readings in approximately 2 seconds, stores up to 1024 measurement results, and allows users to configure scan times, measurement type, revision information, sample ID and calendar settings.

The catalogue's specification table lists the RFM950 and RFM970 together, with the RFM970 additionally identified as having thermostatic temperature control of room temperature ±10°C. The RFM950 does not have a specified thermostatic control range in the table.
