The Labmart LMAR1317T Touchscreen Abbe Refractometer is a fully automatic refractometer for measuring the refractive index of transparent, translucent liquids and solid substances, as well as Brix of sugar solutions. It features a 1.30000–1.72000 nD range, 0.00001 resolution, -20°C to +120°C temperature range, 500-data memory, 589 nm LED illumination and touchscreen operation.

3. Detailed Product Description

Product Overview

The LMAR1317T Touchscreen Abbe Refractometer is a laboratory instrument designed for measurement of refractive index (nD) and Brix (BX). The instrument can measure the refractive index of transparent or translucent liquid and solid substances and can determine the Brix value of sugar solutions.

The system provides automatic correction of the temperature effect on Brix and can display the temperature of the sample. A touchscreen interface provides access to measurement functions, while the instrument uses a 589 nm LED light source and a hard-glass prism.

The LMAR1317T provides a refractive-index range of 1.30000–1.72000 nD with 0.00001 resolution and stores up to 500 data sets. Sample temperature can additionally be controlled using an optional refrigerated circulating bath.
