Automatic Digital Refractometer SGW-733 / SGW-731

Overview

Product Overview

The AELAB SGW-733 and SGW-731 are Automatic Digital Refractometers designed for automatic measurement of refractive index and Brix. Both models provide a refractive index (nD) measuring range of 1.30000–1.70000 and a Brix range of 0–100%.

The instruments use a high-resolution CCD detection system for fully automatic measurement and provide refractive index accuracy of ±0.0002 with ±0.00001 resolution. Brix measurement accuracy is ±0.1% with ±0.01% resolution.

Both models use a 7 inch color touch screen, hard glass prism, 1000-set data storage and RS232, USB and U Disk interfaces. SGW-733 additionally provides built-in Peltier temperature control, with a temperature display range of 0–90℃, control range of 10–60℃ and control accuracy of ±0.1℃.
