HengaoDe HAD-S45A Portable Spectrophotometric Colorimeter with 45°/0° Geometry

Overview

The HengaoDe HAD-S45A is a handheld spectrophotometric colorimeter engineered for precision color measurement in industrial quality control environments where portability, speed, and metrological traceability are critical. Based on the 45°/0° optical geometry—compliant with ISO 7724-1 and CIE No. 15—the instrument replicates human visual perception under standardized illumination by excluding specular reflection (SCI mode), ensuring consistency across diverse surface finishes including glossy plastics, coated metals, textiles, and printed materials. Its spectral sensor covers the full visible range (400–700 nm) at 10 nm resolution, enabling accurate calculation of CIE L*a*b*, ΔE*ab, and spectral reflectance curves. Designed for field deployment and production-floor use, the HAD-S45A delivers laboratory-grade repeatability (ΔE*ab ≤ 0.05) without requiring external software or smartphone pairing—making it suitable for rapid pass/fail evaluation in automotive trim inspection, packaging validation, paint formulation, and road signage compliance testing.

Key Features

• Optical architecture compliant with ISO 7724-1, ASTM E308, and GB/T 3978–2008 for geometrically consistent color assessment.
• High-stability solid-state LED illumination with D65 standard illuminant; optional multi-illuminant support (D50, A, F2, etc.) in HAD-S45B variant.
• Integrated 1.14″ full-color LCD with intuitive rotary encoder interface—enabling real-time switching between color spaces (L*a*b*, L*C*h*, XYZ, Yxy), delta metrics (ΔE*ab, ΔE*00), and spectral plots without app dependency.
• Self-calibrating system using a proprietary 92% reflectance ceramic white tile, thermally stable and resistant to yellowing or abrasion over extended service life.
• Rugged anodized aluminum housing (Ø32 × 90 mm, 90 g) rated for industrial handling; IP54-equivalent ingress protection against dust and splashing water.
• Sub-second measurement cycle (~1 s), optimized for high-throughput sampling on moving production lines or mobile lab applications.
• Built-in non-volatile memory supporting firmware updates and user-defined tolerances; calibration history and measurement logs retained locally.

Sample Compatibility & Compliance

The HAD-S45A accommodates flat, curved, and textured substrates within its 8 mm aperture—ideal for measuring automotive interior panels, extruded plastic profiles, textile swatches, coil-coated steel, and traffic-grade retroreflective sheeting. It meets national verification requirements per JJG 595–2019 (China’s mandatory metrological regulation for colorimeters), and supports traceable calibration through certified reference tiles traceable to NIM (National Institute of Metrology, China). While not CE-marked or FDA-registered, its measurement methodology aligns with ISO 11664-4 (CIE colorimetry) and ASTM D2244 (color difference calculation), facilitating integration into ISO 9001-certified QA workflows. For regulated industries requiring audit-ready documentation, optional PC software provides GLP-compliant reporting with timestamped metadata, operator ID fields, and digital signature support.

Software & Data Management

The device operates autonomously via embedded firmware but interfaces seamlessly with HengaoDe’s cross-platform software suite (Windows/macOS/iOS/Android) for advanced analysis. The application enables batch export of spectral data (.csv/.spc), generation of tolerance ellipses in CIELAB space, statistical process control (SPC) charting, and comparative analysis across multiple instruments. All raw spectral readings are stored onboard with timestamps and user annotations. Data exports include full metadata: illuminant, observer angle, measurement date/time, instrument serial number, and calibration status—supporting 21 CFR Part 11 readiness when deployed with role-based access controls and electronic audit trails. Firmware updates are delivered via USB-C or Bluetooth LE, preserving configuration integrity during version upgrades.

Applications

• Automotive: Validation of dashboard trims, seat fabrics, and exterior paint batches against OEM color standards (e.g., BMW GS95024, Ford WSS-M99P1111-A).
• Printing & Packaging: Spot-checking CMYK spot colors, metallic inks, and laminated films for conformance to GRACoL or SWOP specifications.
• Plastics & Coatings: Monitoring batch-to-batch consistency in injection-molded components and powder-coated architectural aluminum.
• Textiles & Apparel: Assessing dye lot uniformity across woven/knitted goods under retail lighting conditions (CWF, TL84).
• Regulatory Compliance: Verifying retroreflectivity and chromaticity of highway signage per EN 12899-1 and FHWA MUTCD Section 2A.08.

FAQ

Does the HAD-S45A require annual recalibration by an accredited lab?

No—its internal calibration routine, executed daily or before critical measurements using the included ceramic tile, satisfies routine verification per JJG 595–2019. Accredited recalibration is recommended every 12 months for ISO/IEC 17025-compliant labs.

Can the device measure transparent or translucent samples?

Not directly—the 45°/0° geometry is optimized for opaque, diffusely reflecting surfaces. Translucent films or liquids require a transmission accessory (sold separately) and a dedicated instrument model.

Is the spectral data compatible with third-party color management systems (e.g., X-Rite Color iMatch, Datacolor Match Pigment)?

Yes—exported .csv files contain wavelength-intensity pairs at 10 nm intervals and can be imported into industry-standard color formulation software for spectral matching and metamerism analysis.

What is the warranty coverage and service support structure?

HengaoDe provides a 24-month limited warranty covering parts and labor. Technical support includes remote diagnostics, firmware patches, and access to regional service centers in Shanghai, Beijing, and Guangzhou—with typical turnaround under 5 business days for hardware repair.

How does the HAD-S45A handle ambient light interference during outdoor use?

Its pulsed LED illumination and synchronous detection circuitry reject ambient photometric noise, enabling reliable operation under daylight (up to 10,000 lux) without shielding hoods or dark enclosures.
