3nh Colorimeter Selection Guide

Why Choosing the Right Colorimeter

Selecting a colorimeter isn’t just about picking a measurement tool—it’s about protecting your brand reputation, optimizing production efficiency, and ensuring consistent quality across every product. The wrong instrument can lead to costly reworks, customer complaints, and missed market opportunities.

Choosing the right colorimeter is critical to ensuring accurate color measurement, efficient quality control, and seamless color management across your workflows. This guide will help you select the ideal 3nh colorimeter based on application scenarios, sample types, precision requirements, and portability needs.

Choose the Right Colorimeter for your industrial application

Choosing the right colorimeter involves considering multiple factors beyond just whether the substrate is opaque, translucent, or transparent. Here’s a comprehensive guide to help you select the most suitable device for your needs:

1. Substrate Properties

A. Opacity/Transparency

• Opaque Materials(e.g., plastics, paints, textiles, metals):

• Use reflectance-mode colorimeters(most standard models).

• Key consideration: measurement aperture size(e.g., 4mm, 8mm) to match the sample’s surface texture or feature size (e.g., small parts may require a smaller aperture like 4mm).

• Translucent/Transparent Materials(e.g., glass, films, liquids, semi-transparent plastics):

• Choose transmittance-mode colorimeters(ensure the device supports this function).

• Example: Measure the color of a clear plastic film by placing it between the light source and sensor.

B. Surface Texture

• Smooth vs. Rough Surfaces:

• Smooth surfaces (e.g., polished metals, glossy plastics) may require gloss compensation(some advanced models like 3NH’s TS7030 offer this).

• Rough or uneven surfaces (e.g., textiles, matte plastics) need a colorimeter with a stable contact areaand possibly a larger aperture to average measurements.

  
  

Optical geometry directly impacts measurement accuracy—match it to your sample characteristics:

C. Thickness and Geometry

• Thick or irregularly shaped objects may require a handheld, portable model(e.g., 3NH’s NH300) for easy maneuverability.

• Thin films or layered materials may need a tabletop modelwith a fixed measurement platform for precision.

2. Measurement Requirements

A. Color Space and Parameters

• Ensure the colorimeter supports the color spaceyou need (e.g., CIE Lab*, RGB, CMYK).

• For industry-specific metrics (e.g., whiteness, yellowness, opacity), check if the device includes these pre-programmed indices.

B. Accuracy and Repeatability

• High-Precision Needs(e.g., automotive paints, medical devices):

• Look for models with low ΔE repeatability (e.g., ΔE ≤ 0.03, like 3NH’s NR10QC).

• General Quality Control:

• A mid-range model (ΔE ≤ 0.1) may suffice (e.g., 3NH’s NH300 with ΔE < 0.07).

C. Measurement Aperture

• Match the aperture size to your sample:

• Small objects (e.g., buttons, fibers): 4mm or smaller aperture (e.g., NR60CP with 4mm/8mm switchable).

• Large, uniform surfaces: 8mm or larger aperture (e.g., TS7030’s Ø8mm platform).

• Specialized needs (e.g., curved surfaces, narrow gaps): Models with tip apertures(e.g., TS7030’s tip aperture for hard-to-reach areas).

3. Industry and Application

Meet Industry Standards & Regulatory Requirements

Many industries have strict color-related regulations and standards: 

Food & Beverage: Color consistency indicates freshness (e.g., fruit juices, baked goods) and compliance with FDA/EFSA guidelines. 

Automotive: OEMs require adherence to precise color specs for paint and interior materials (e.g., ISO 105-J01 for textiles). 

Medical Devices: Color-coded components must meet biocompatibility and visibility standards (e.g., ASTM E308 for color measurement). 

A specialized colorimeter (e.g., multi-angle models for automotive coatings, UV-compatible units for food) ensures you meet these requirements and avoid fines or product recalls.

3nh Colorimeter Series Recommendation Chart

A. Common Industries and Recommendations

• Plastics/Automotive:

• Require high accuracy and gloss compensation. Choose models like 3NH TS7030(supports gloss measurement and multiple apertures).

• Textiles/Printing:

• Need portability and multi-aperture options for fabric swatches or printed materials. 3NH NR10QC(dual positioning, auto-calibration) is ideal.

• Food/Beverages/Liquids:

• Transmittance-mode measurement is critical. Look for models with a transmittance accessory(e.g., cuvette holders for liquid samples).

• Research/Laboratories:

• Require advanced features like spectral data outputor PC software integration (e.g., 3NH CQCS3 software for trend analysis). Prioritize bench-top spectrophotometers (e.g., YS6010, TS8298). These instruments offer high precision, multiple measurement modes (reflectance/transmittance/haze), and compatibility with professional color management software, making them ideal for formula development, material analysis, and batch consistency testing in industries like paints, plastics, and pharmaceuticals.

B. Compliance with Standards

• Ensure the device meets industry standards (e.g., ISO, ASTM, DIN) for your application (e.g., ISO 11664 for color spaces, ASTM E313 for whiteness). 

4. Operational and Functional Features

A. Ease of Use

• Calibration:

• Auto-calibration (e.g., NH300’s boot-up calibration) or built-in white board (e.g., NR10QC) reduces setup time.

• Ergonomics:

• Handheld models should be lightweight and comfortable for long-term use (e.g., NH300’s ergonomic design).

B. Data Management

• PC Software Compatibility:

• Models with software (e.g., CQCS3) enable data storage, trend analysis, and report generation (critical for QC documentation).

• Connectivity:

• Bluetooth/Wi-Fi capabilities (e.g., NR110) allow real-time data transfer to smartphones or computers.

C. Power and Portability

• Field Use:

• Prioritize rechargeable lithium batteries (e.g., NH300: 5,000+ measurements per charge) and compact design. Portable/handheld colorimeters designed for mobility, they feature battery-powered operation, durable construction, and one-click measurement, perfect for on-site inspections of automotive coatings, architectural paints, and printed products.

• Bench Use:

• Tabletop models may offer more advanced features but require a stable setup.

5. Budget and Long-Term Needs

• Entry-Level:

• General Precision (ΔE*ab ≤ 0.04–0.1) Basic handheld models (e.g., 3NH NH200) for small businesses or occasional use (cost-effective, suitable for simple color comparison).

• Mid-Range:

• High Precision (ΔE*ab ≤ 0.01–0.03) Models like NH300 or NR10QC balance accuracy and affordability for most industrial applications.

• High-End:

• Advanced devices (e.g., TS7030) with multi-apertures, gloss measurement, and extended light source life (ideal for large enterprises or rigorous QC). Choose models like TS70 series, TS8298 for R&D, critical quality control in automotive and high-end coatings industries, where color consistency is paramount.

6. Additional Considerations

• Gloss Measurement:

  If you need to assess both color and surface gloss, consider combined colorimeter-gloss meter devices(e.g., 3NH’s integrated solutions).

• Transmittance/Haze Measurement:

  For transparent materials (glass, films, coatings), select YS6010, TS8298 (supports both reflectance and transmittance).

• Fluorescent Sample Testing:

  Prioritize instruments with UV light sources (e.g., YS4580, YS6010) to capture accurate color data for fluorescent paints and inks.

• Large Sample Measurement:

  Opt for YS4580 (20mm aperture) for architectural coatings, traffic signs, and other large-surface samples.
  

• Multi-User Environments:

  Look for models with user profile management or password protection to ensure consistent settings across operators.  Ensure the instrument integrates with your existing workflow (e.g., production line systems, color management software).

• After-Sales Support:

  Check for calibration services, warranty, and technical support (e.g., 3NH’s global service network).
