S-Series III Color Analyzer

The S‑SERIES III is a reflectance measurement spectrophotometer built for small particulate or  color-homogenous food products. The analyzer provides fast, objective results in an easy-to-understand format, helping operators maintain quality control in food manufacturing with minimal or no sample preparation.

This unit is compact and built for industrial environments, offering consistent performance even on busy production lines. Operators can measure products in their natural form without requiring extensive milling or sorting. The S‑SERIES/III delivers accurate color or appearance scores, allowing production teams to make confident batch and process decisions quickly,

The analyzer measures reflected light across multiple color bands to produce precise numeric scores. Several measurement modes are available:

• Four-color reflectance: Measures red, green, blue, and yellow bands simultaneously.
• Single-color reflectance: Focuses on one selected color band.
• Appearance mode: Combines multiple bands into a single score for overall visual quality.
• Brightness mode: Measures overall lightness and darkness.
• Optional ratio mode: Evaluates product-specific variables, such as tomato maturity or pigment changes.

With automated calibration and a stable light source, the S‑SERIES III provides repeatable results that minimize guesswork and streamline process decisions.

The S‑SERIES III is ideal for fine ingredients and homogenous products. It helps maintain quality and consistency with a variety of food products, such as;

• Flours, powders, and food pigments
• Spices, seeds, and slurries
• Processed products like sauces and condiments

Operators can use the analyzer to monitor color changes from baking, roasting, frying, or drying. While many associate color with coffee roast, Agtron provides specialized analyzers for coffee where near-infrared technology measures chemistry beyond the visual spectrum for precise roast classification.

Agtron offers other analyzers to fit different production needs:

• M‑SERIES III: Measures larger products such as nuts, chips, and baked goods. The analyzer evaluates a wide sample area without requiring milling or selective sorting.
• E20CP-III: Uses near-infrared to classify coffee roasts and cocoa beans, providing data on aroma and flavor-related compounds.
• E30FP-III: Hybrid VIS/NIR analyzer for par-fried or post-fried potato and snack products.
• M-BASIC II: Entry-level NIR coffee analyzer for smaller roasters.

Each model is built for industrial use, delivering fast, repeatable results that support production efficiency and consistent quality.

Our analyzers provide consistent readings that reduce product variability, save time, and support confident production decisions. The S‑SERIES III gives operators clear, actionable data without overcomplicating sample preparation or analysis.
