A 50mm measurement aperture accommodates coffee bean samples, and the 7-inch touchscreen presents SCAA\/Agtron, HCCI, roast-degree and CIE Lab readings. The benchtop format suits roasters who need a consistent numerical record alongside their existing roast assessment.\u003c\/p\u003e\u003cfigure\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0273\/2133\/5851\/files\/coffee-roast-colorimeter-ls177c-roast-index-display.jpg?v=1793766555\" alt=\"LS177C display showing SCAA, HCCI and roast color readings\" width=\"990\" height=\"610\" loading=\"lazy\" style=\"max-width:100%;height:auto;\"\u003e\u003cfigcaption\u003eLS177C display showing SCAA, HCCI and roast color readings\u003c\/figcaption\u003e\u003c\/figure\u003e\u003ch3\u003eRoast indices and color comparison\u003c\/h3\u003e\u003cp\u003eThe LS177C uses D\/8 SCI optical geometry with a D65 illuminant and 10-degree observer. A measurement takes approximately 1.5 seconds. Coffee-specific sample dishes provide a repeatable way to present the material over the opening. Keep the fill level and bean placement consistent when comparing batches, since an uneven sample surface can affect the reading.\u003c\/p\u003e\u003cp\u003eUse the roast-index display to record a batch result, or compare a sample with a saved reference using CIE Lab and ΔE*ab. Color readings describe the measured sample appearance. Roast-profile decisions can then incorporate the other checks used in your production process.\u003c\/p\u003e\u003ch3\u003eInstrument details\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eModel\u003c\/th\u003e\n\u003ctd\u003eLinshang LS177C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eCoffee outputs\u003c\/th\u003e\n\u003ctd\u003eSCAA\/Agtron number, HCCI and roast degree\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eColor outputs\u003c\/th\u003e\n\u003ctd\u003eCIE Lab and ΔE*ab\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eAperture \/ geometry\u003c\/th\u003e\n\u003ctd\u003e50mm \/ D\/8 SCI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eIlluminant \/ observer\u003c\/th\u003e\n\u003ctd\u003eD65 \/ 10 degrees\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eMeasurement time\u003c\/th\u003e\n\u003ctd\u003eApprox. 1.5s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eRepeatability\u003c\/th\u003e\n\u003ctd\u003eStandard deviation ΔE*ab ≤0.03 for 30 white-tile readings at 3s intervals after calibration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eInter-instrument agreement\u003c\/th\u003e\n\u003ctd\u003eΔE*ab ≤0.4, average of 12 BCRA II tiles\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eTouchscreen\u003c\/th\u003e\n\u003ctd\u003e7-inch, 1024 x 600\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003ePower input\u003c\/th\u003e\n\u003ctd\u003eAC 100–277V, 50\/60Hz, 0.4A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eConnectivity \/ net weight\u003c\/th\u003e\n\u003ctd\u003eUSB and Bluetooth \/ approx. 3.29kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cfigure\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0273\/2133\/5851\/files\/coffee-roast-colorimeter-ls177c-user-calibration.jpg?v=1793766564\" alt=\"LS177C user calibration settings for coffee roast indices\" width=\"990\" height=\"664\" loading=\"lazy\" style=\"max-width:100%;height:auto;\"\u003e\u003cfigcaption\u003eLS177C user calibration settings for coffee roast indices\u003c\/figcaption\u003e\u003c\/figure\u003e\u003ch3\u003eCalibration and reporting\u003c\/h3\u003e\u003cp\u003eWhite-tile calibration establishes the optical reference.
