The RFM970 Automatic Digital Refractometer is a touchscreen laboratory refractometer for measuring the refractive index of transparent and semi-transparent liquids and Brix of sugar solutions. It offers 0.00001 nD resolution, 0–100% Brix measurement, automatic temperature correction, thermostatic temperature control, 1024-result memory and approximately 2-second reading time.

3. Detailed Product Description

Product Overview

The Labmart RFM970 Automatic Digital Refractometer is designed for automated measurement of refractive index (nD) and Brix (BX) in suitable liquid samples. It can be used for transparent and semi-transparent liquids and for determining the Brix value of sugar solutions.

A key feature of the RFM970 is its thermostatic temperature control of room temperature ±10°C, allowing temperature-controlled refractive-index and Brix measurements. The instrument automatically corrects the effect of temperature on Brix and displays the sample temperature.

The touchscreen interface provides access to measurement functions and user-configurable settings such as scan times, measurement type, revision information, sample ID and calendar. The system can store up to 1024 measurement results, with password-protected calibration and USB/RS232C connectivity.
