The purpose of this article is to simplify the instrument selection process by explaining the key differences between Agera L2 and ColorFlex L2 in a way that aligns with how customers actually evaluate color in real-world applications. By outlining how each instrument handles illumination, UV content, geometry, dark-sample accuracy, fluorescence, texture, and everyday Pass/Fail workflows, the article helps users quickly identify which solution best fits their products, industry, and quality objectives. Whether a customer needs precise daylight appearance matching or reliable routine QC, this guide provides a transparent and confident path to the right choice.
1. Both instruments are excellent—your material determines the best fit. Agera L2 and ColorFlex L2 are designed for different application spaces, and choosing the right one depends on whether your materials require calibrated D65/UV, gloss, dark-sample accuracy, or simply fast and reliable Pass/Fail QC.
2. Appearance-driven or complex materials typically require Agera L2. If your products include fluorescence, texture, gloss variation, OBAs, or very dark colors—or if you need strong agreement across multiple sites—the Agera L2 provides the advanced illumination and geometry required for accurate results.
3. For simple, non-fluorescent, uniform materials, ColorFlex L2 delivers exceptional value. When color evaluation is routine, stable, and non-appearance-critical—such as in food ingredients, powders, stable plastics, or processed goods—ColorFlex L2 provides dependable performance with a streamlined workflow.
Selecting the correct color measurement instrument is an important decision—one that directly affects product quality, brand consistency, compliance, and customer confidence. While many materials can be measured using a standard Pass/Fail system, others require more advanced illumination, geometry, UV handling, and dark-sample precision to ensure results that match what the human eye sees in real daylight.
This guide provides a clear, customer-friendly explanation of Agera L2 and ColorFlex L2, and a practical framework to help you choose the right instrument for your materials and workflow.
Introducing the Two Instruments: Agera L2 & ColorFlex L2
Agera L2 — Advanced Appearance Measurement for Complex Materials
Agera L2 is designed for applications where accuracy, appearance, and material complexity require more than simple Pass/Fail evaluation. It features:
- True, ISO-Calibrated D65 illumination
- Calibrated UV for OBAs, bright whites, and fluorescents
- Ultra Dark Mode for samples below 20% reflectance
- 0°/45° circumferential geometry for exceptional visual correlation
- Integrated 60° gloss measurement
- Imaging to assist with textured and patterned materials
- Superior inter-instrument agreement for multi-site operations
- HunterLab Essentials L2 on-board software
- Ethernet TCP/IP connectivity to LIMS/SPC integration
Agera L2 is ideal when consistent appearance under daylight is critical, or when your materials have texture, fluorescence, gloss, deep color, or process-driven variation.
ColorFlex L2 — Reliable, Robust, Everyday Color QC
ColorFlex L2 is built for high-volume, routine quality control where materials are smooth, uniform, and non-fluorescent. It offers:
- 45°/0° annular geometry
- Stable Pass/Fail performance
- Excellent repeatability for solid colors
- Imaging to assist with textured and patterned materials
- HunterLab Essentials L2 on-board software
- Ethernet TCP/IP conectivity to LIMS/SPC integration
- Affordable, simple operation
- Fast QC throughput
ColorFlex L2 is the preferred solution for food ingredients, powders, sauces, stable plastics, coatings, processed goods, and many other everyday materials where appearance challenges are minimal.
What to Buy and Why: A Practical Decision Guide
Below is a simple, customer-friendly way to identify the right instrument for your material type and quality requirements.
1. Does your material fluoresce—or contain brighteners?
Examples: OBAs in plastics or paper, safety colors, textile brights, fluorescent inks.
- Yes → Agera L2
- No → Go to Step 2
2. Is your material very dark (below ~20% reflectance)?
Examples: carbon-black plastics, deep navy, matte appliance finishes, dark coatings.
- Yes → Agera L2 (Ultra Dark Mode)
- No → Go to Step 3
3. Does your material have texture, directionality, or pattern?
Examples: woven textiles, molded plastics, rough coatings, films, embossed packaging.
- Yes → Agera L2
- No → Go to Step 4
- Yes → Agera L2
- No → Go to Step 5
5. Do you have multiple labs, suppliers, or plant locations that must agree?
- If daylight-based visual agreement across locations is important → Agera L2
6. Is this primarily simple Pass/Fail QC of stable, non-fluorescent materials?
- If yes → ColorFlex L2
- If not → Agera L2
