Manufactured by\u00a0<strong>Lasany International<\/strong>\u00a0under 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 \u00b10.0002 nD and resolution of \u00b10.0001 nD, while simultaneously measuring Brix from 0\u2013100% with \u00b10.1% accuracy. A standout feature of the LI-R501 is its automatic temperature correction for Brix \u2014 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.<\/p>\n<\/div>\n<div class=\"section\">\n<h2 class=\"section-title\"><strong>Key features<\/strong><\/h2>\n<div class=\"features-grid\">\n<ul>\n<li class=\"feat-card star\"><i class=\"ti ti-eye\"><\/i><strong>Dual visual aim + LCD<\/strong>Monocular telescope for visual aiming combined with LCD digital display for precise, direct readout.<\/li>\n<li class=\"feat-card star\"><i class=\"ti ti-temperature\"><\/i><strong>Auto Brix temp. correction<\/strong>Automatically corrects Brix readings for sample temperature \u2014 no manual conversion tables required.<\/li>\n<li class=\"feat-card\"><i class=\"ti ti-list-numbers\"><\/i><strong>4 measurement modes<\/strong>Refractive index (nD), Brix, Brix TC (temperature corrected), and automatic temperature display.<\/li>\n<li class=\"feat-card\"><i class=\"ti ti-diamond\"><\/i><strong>Hard glass prism<\/strong>Durable optical prism resistant to chemical corrosion and scratching for long laboratory service life.<\/li>\n<li class=\"feat-card\"><i class=\"ti ti-usb\"><\/i><strong>RS-232 + software<\/strong>RS-232 data output with included software CD for PC connectivity and data management.<\/li>\n<li class=\"feat-card\"><i class=\"ti ti-adjustments\"><\/i><strong>Temperature display<\/strong>Built-in temperature display (0\u201350\u00b0C, min. 0.1\u00b0C) for full sample thermal reference during measurement.<\/li>\n<li class=\"feat-card\"><i class=\"ti ti-package\"><\/i><strong>Complete accessory kit<\/strong>Supplied with calibration standard, hex key, lamps, fuses, RS-232 cable, software CD, and manuals.<\/li>\n<li class=\"feat-card\"><i class=\"ti ti-school\"><\/i><strong>Industry &amp;
