Description
The Lasany LI-R501 Digital ABBE Refractometer is a versatile, precision optical instrument that combines the reliability of the classic Abbe refractometer design with digital readout technology — delivering accurate, repeatable measurement of the refractive index nD and Brix of transparent and sub-transparent liquid and solid samples across four dedicated measurement modes. Manufactured by Lasany International under ISO 9001:2015 certification in Panchkula, Haryana, the LI-R501 is widely used in petroleum, chemical, pharmaceutical, sugar refining, and food industries, as well as in colleges, universities, and scientific research institutions across India and globally. The LI-R501 measures refractive index across the range of 1.30000 to 1.70000 nD with an accuracy of ±0.0002 nD and resolution of ±0.0001 nD, while simultaneously measuring Brix from 0–100% with ±0.1% accuracy. A standout feature of the LI-R501 is its automatic temperature correction for Brix — automatically compensating for the effect of sample temperature on Brix readings without manual correction tables, ensuring accurate sugar concentration data regardless of ambient laboratory conditions. With a hard glass prism, monocular telescope system for visual aim, LCD digital display for direct readout, RS-232 output for PC connectivity, and software included as standard, the LI-R501 provides a complete digital Abbe refractometer solution with comprehensive accessories including calibration standard, replacement lamps, fuses, RS-232 cable, software CD, and operating manual.

Why choose the LI-R501?
- Classic Abbe precision with modern digital readout — the LI-R501 retains the hard glass prism and monocular telescope system of the traditional Abbe refractometer — the gold standard in refractive index measurement for over 100 years — while adding digital LCD readout and RS-232 data output, delivering the best of both proven optical design and contemporary digital laboratory workflow.
- Automatic Brix temperature correction saves analyst time — the built-in automatic Brix TC mode continuously compensates for sample temperature variation, eliminating the time-consuming manual correction calculations that traditional Abbe instruments require — a significant operational advantage in busy food, beverage, and sugar industry quality control environments.
- Widest application range in the Lasany refractometer series — covering petroleum, chemicals, pharmaceuticals, sugar, food, and academic use cases, the LI-R501’s broad nD range of 1.30000–1.70000 and 0–100% Brix coverage makes it the most versatile refractometer in the Lasany range for multi-industry laboratories.
- Complete out-of-box solution with all accessories included — unlike bare-instrument competitors, the LI-R501 ships with calibration standard, spare lamps, spare fuses, RS-232 cable, software CD, dust cover, and full operating manual — ensuring the instrument is ready for immediate deployment without additional procurement.
- ISO 9001:2015 certified Indian manufacturer with global reach — manufactured by Lasany International in Panchkula with CE certification and active after-sales support across India and internationally, the LI-R501 delivers internationally benchmarked optical performance at a competitive Indian manufacturer price point.
