Overview
The PREMOSYS PR0086-S is an industrial-grade online color measurement system engineered for high-precision absolute colorimetry in dynamic production environments and controlled laboratory settings. Based on the CIE 1976 L*a*b* color space, it employs a calibrated 6500 K LED light source and a fixed-optic spectral detection path covering the visible spectrum from 400 to 700 nm—fully aligned with the CIE standard observer (2°) and CIE illuminant D65. Unlike portable or benchtop colorimeters relying on relative calibration, the PR0086-S undergoes factory absolute calibration using a traceable spectral radiance reference instrument, ensuring metrological integrity across installations. Its design targets continuous process monitoring where color consistency is critical to product conformity, regulatory compliance, and brand integrity—particularly in industries subject to ISO 11664, ASTM E308, and ISO 9001 quality management requirements.
Key Features
- Factory-traceable absolute calibration against primary spectral radiance standards, enabling inter-system comparability without site-specific recalibration.
- Robust stainless-steel housing (2 mm thickness) with dust-resistant coating, rated for industrial ambient conditions from 10 °C to 55 °C.
- Differential measurement architecture with real-time temperature compensation, minimizing thermal drift during extended operation.
- Fixed-focus optical geometry optimized for 70 mm working distance, delivering consistent Ø70 mm measurement area with minimal edge effects.
- 10 Hz acquisition rate supports high-speed inline inspection of moving substrates (e.g., extruded films, printed webs, coated panels).
- RS485 serial interface ensures noise-immune communication over distances up to 1,200 m in electrically noisy factory environments.
- Integrated 6500 K LED illumination provides stable, flicker-free, and spectrally reproducible excitation—eliminating lamp aging artifacts common in xenon or halogen sources.
Sample Compatibility & Compliance
The PR0086-S is designed for non-contact reflectance measurement of flat or gently curved surfaces with diffuse or semi-specular reflectance characteristics. It supports routine evaluation of pigmented polymers, painted metals, textiles, food packaging, and consumer packaged goods—including matte, glossy, and textured finishes. The optional PR0086-S-70-15 variant incorporates a 15° viewing angle optimized for specular reflection suppression on highly reflective materials (e.g., lacquered automotive parts or metallic foils). All configurations comply with CIE Publication No. 15:2018 and support traceable reporting per ISO/IEC 17025 when integrated into accredited testing workflows. The system meets electromagnetic compatibility (EMC) requirements per EN 61326-1 and carries CE marking for use within the European Economic Area.
Software & Data Management
The PR0086-S communicates raw and processed color data—including L*, a*, b*, ΔEab, chromaticity (x, y), and CIE XYZ tristimulus values—via standardized ASCII protocol over RS485. A certified WIN32 DLL enables seamless integration into SCADA, MES, and custom QA/QC applications running on Windows-based industrial PCs. Data logging supports timestamped batch records with embedded environmental metadata (temperature, measurement ID, operator code). When deployed in regulated environments (e.g., pharmaceutical packaging or automotive Tier-1 supply chains), the DLL supports audit trail generation and user-access controls compatible with FDA 21 CFR Part 11 requirements when paired with validated host software and procedural controls.
Applications
This system is routinely deployed for real-time color verification in continuous manufacturing processes such as film extrusion, coil coating, label printing, and food product sorting. Validated use cases include batch-to-batch color consistency monitoring for flooring materials in large-scale hospitality projects (e.g., Dubai hotel refurbishments), shade control during snack food packaging (e.g., Lay’s potato chip bag lamination), and incoming raw material verification for pigment masterbatches. Its stability and repeatability make it suitable for establishing in-house color tolerance limits aligned with customer-specific AQL sampling plans per ISO 2859-1.
FAQ
Is the PR0086-S suitable for measuring transparent or translucent materials?
No—it is optimized for opaque and diffusely reflecting surfaces. Translucent or backlit samples require specialized transmission-mode instrumentation.
Can the device be recalibrated onsite by the user?
Yes, via the included calibration tile and DLL-supported procedure; however, factory absolute calibration remains the reference baseline for metrological traceability.
Does the system support multiple color spaces beyond CIELAB?
Raw spectral data is not output; only CIELAB, CIE xyY, and XYZ are provided. Conversion to other spaces (e.g., LCH, CMYK) must occur in host software.
What is the recommended maintenance interval?
Optical window cleaning every 2 weeks in dusty environments; full verification against reference tile quarterly or per shift change in GMP-critical lines.
Is Ethernet or USB connectivity available?
No—only RS485 is supported. Integration with Ethernet networks requires an external RS485-to-Ethernet converter compliant with Modbus RTU protocol.
