Digital Bench-top Refractometer (RA-620/RA-600)

Digital Bench-top Refractometer (RA-620/RA-600) Instrument Introduction:

The new generation refractometer (RA-620/RA-600) from Kyoto Electronics Manufacturing Co., Ltd. (KEM) of Japan is designed for easy operation and space-saving liquid refractive index measurement. There are two models: the high-precision RA-620 and the wide-range RA-600. The RA-620 achieves world-class high precision with an accuracy of ±0.00002. The RA-600 has a broad measurement range of 1.3200 to 1.7000. The footprint is half that of previous models (RA-520N/RA-500N), with dimensions that fit on an A4 sheet of paper. Power consumption is 20W, half that of previous models. In terms of functionality, it features a color LCD display and touch panel, with USB and LAN as standard interfaces, accommodating various expansion devices.

Kyoto Electronics Manufacturing Co., Ltd. (KEM) is a manufacturer of refractive index standard liquids certified by Japanese national standards. Refractive index standard liquids can be used to check the refractometer (RA-620/RA-600), providing users with high-precision and highly reliable analysis results.

Digital Bench-top Refractometer (RA-620/RA-600) Main Features:

1. Bench-top refractometer with touch digital LCD screen, displaying refractive index, Brix, and concentration.
2. Built-in automatic temperature control, compact design, easy operation, and fast measurement speed.
3. Uses LED light source, no need to replace bulbs; measuring prism is sapphire for wear resistance.
4. Digital refractometer complies with GLP standards, storing results, inspection, and calibration records.
5. Optional fully automatic sample injection cleaning device or multi-sample auto-sampler available.
6. Refractometer can input refractive index and concentration conversion tables to calculate sample concentration.
