Professional Linshang LS177 & LS177C Large Aperture Spectrocolorimeter Series (Malaysia)

For high-precision powder color measurement, masterbatch comparison, pharmaceutical pill testing, textile color control, and specialized coffee bean roast degree grading (SCAA / HCCI evaluation), having a desktop spectrophotometer with an ultra-large aperture is essential. MTM Precision Sdn. Bhd. is proud to present the official Linshang LS177 and LS177C Large Aperture Spectrocolorimeter Series technical documentation in clean English.

The Linshang LS177 / LS177C Series consists of advanced desktop spectrophotometers featuring an impressive 50mm ultra-large test aperture and adopting the international standard D/8 illumination geometry (Specular Component Included). Engineered specifically for non-transparent powders,masterbatches, granules, pills, fabrics, and irregular samples, these instruments average out surface irregularities to deliver exceptional measurement stability. While the LS177 focuses on general powder whiteness, masterbatch color matching, and industrial quality control across paint, plastic, food, and medicine,the specialized LS177C is calibrated to measure SCAA scores, HCCI values, and roast degrees for coffee beans.

Below is an extensive technical breakdown of the product introduction, model differences, core applications,key advantages, and operational features for the LS177 and LS177C models, presented cleanly in plain text without tables, citations, LaTeX symbols, or encoding errors.

Model Contrast & Specialization

Linshang LS177 (Large Aperture Spectrocolorimeter):
- Primary Focus: General industrial powder color measurement, whiteness testing, masterbatch comparison, polymer pellets, pharmaceutical pills, and fabric color quality control.
- Key Function: Comprehensive color spaces, color difference formulas, whiteness/yellowness indices, and spectral reflectance curve analysis.
Linshang LS177C (Specialized Coffee Bean Roast Degree Spectrocolorimeter):
- Primary Focus: Specialized agricultural and food science testing for roasted coffee beans and ground coffee.
- Key Function: Direct measurement of SCAA (Specialty Coffee Association of America) scores, HCCI (Coffee Roast Index) values, and precise roast degree categorization (Light Roast, Medium Roast,Dark Roast, etc.).

Product Applications

Powder Whiteness & Color Analysis: Measuring titanium dioxide, chemical powders, cosmetic powders, flour, and industrial chemicals using the 50mm sample dish.
Plastic Masterbatches & Pellets: Evaluating color consistency, batch variance, and masterbatch color differences for injection molding and extrusion manufacturing.
Coffee Bean Roast Degree Grading (LS177C): Assessing coffee roasting quality by instantly generating SCAA scores, HCCI values, and roast profile classifications.
Pharmaceuticals & Medicine: Non-destructive color verification and shade consistency testing for medicinal capsules, tablets, and pills.
Textiles & Fabrics: Analyzing textured fabrics, non-woven materials, and woven garments where a large measurement area is required to eliminate pattern bias.
Paints, Coatings & Inks: Quality control for solid pigment powders, dried paint flakes, and opaque coatings.

Key Features & Operational Advantages

50mm Ultra-Large Test Aperture: Provides an expansive 50mm illumination and viewing area, perfect for powders, granules, coarse textures, and uneven samples that traditional small apertures fail to measure accurately.
D/8 International Illumination Geometry: Adopts the standard D/8 (Specular Component Included / SCI) method to ensure high measurement correlation and global technical standard compliance.
Specialized Coffee Bean Intelligence (LS177C): Pre-programmed with professional coffee evaluation algorithms to output SCAA scores and HCCI roast indices instantly.
Comprehensive Color Parameters & Spectral Curves: Displays full visible light spectral reflectance curves, multiple color spaces (CIE Lab, LCh, etc.), and industry-standard delta color difference formulas ( $\Delta\text$ ).
Intuitive Touch Screen Interface: Equipped with a large color capacitive touch screen featuring clear graphic icons for instant color scanning, standard vs. sample comparison, and data review.
Robust Desktop Form Factor: Built with a stable benchtop housing designed for laboratory counters,QC testing stations, and production line inspection desks.
