Overview
The GBPI SGW-810 Automatic Haze and Luminous Transmittance Tester is an ISO/ASTM-compliant optical measurement instrument engineered for precise, repeatable quantification of haze and luminous transmittance in transparent and translucent planar materials—including plastic films, rigid sheets, packaging substrates, coatings, and liquid media such as pharmaceutical solutions or beverage formulations. It operates on the principle of collimated illumination with diffuse viewing geometry and integrates a calibrated integrating sphere detection system conforming to ASTM D1003–22 (Standard Test Method for Haze and Luminous Transmittance of Transparent Plastics), GB/T 2410–2008 (Plastics—Determination of Haze and Luminous Transmittance), and JIS K7105:1981 (Testing Methods for Transparency and Haze of Plastics). The instrument employs dual CIE-standard illuminants (C-light at 6774 K and A-light at 2856 K), enabling spectral consistency across global regulatory and industrial testing protocols. Its optical architecture eliminates ambient light interference via internal modulation, permitting operation outside darkroom environments while maintaining metrological integrity for large-format samples up to Ø25 mm aperture.
Key Features
- Fully automated microprocessor-controlled operation with intuitive 7-inch capacitive touchscreen interface—no manual knobs or analog adjustments required.
- High-stability dual-CIE light source (C and A illuminants) with thermal regulation to ensure spectral fidelity over extended measurement cycles.
- Integrating sphere photodetector system using calibrated silicon photodiodes, optimized for diffuse transmission capture per ASTM D1003 Annex A2.
- Real-time display resolution: transmittance to 0.01%, haze to 0.01%; minimum discernible change: 0.1% transmittance, 0.01% haze.
- Onboard data storage capacity for up to 800 test records; export via USB 2.0 port or removable USB flash drive (FAT32 formatted).
- Dedicated sample handling accessories: magnetic film clamp for tension-free flat positioning and standardized liquid cuvette (10 mm pathlength) compliant with USP & EP clarity testing conventions.
- Integrated self-diagnostic routine with certified reference haze standard (NIST-traceable calibration check plate included—non-wipeable, clean only with dust blower).
Sample Compatibility & Compliance
The SGW-810 accommodates solid specimens up to 25 mm in diameter and 50 mm in thickness, including PET, PP, PS, PC, acrylic sheets, laminated films, and coated glass. Liquid measurements follow pharmacopeial clarity assessment methodology (USP , EP 2.2.1) using the supplied quartz cuvette. All optical components meet ISO 9001-certified manufacturing tolerances. Instrument validation supports GLP/GMP audit requirements: full electronic audit trail (via optional PC software), user access levels, timestamped results, and CFR 21 Part 11–compliant data integrity when paired with GBPI’s TraceLink™ Lab Suite (v3.2+). Calibration verification aligns with ISO/IEC 17025–2017 clause 6.5.2 for optical instrumentation.
Software & Data Management
The embedded firmware enables direct result visualization, statistical summary (mean, SD, CV%), pass/fail threshold alerts, and CSV export. When connected to a Windows PC via USB, the optional TraceLink™ Lab Suite provides advanced functionality: multi-instrument fleet management, automated report generation (PDF/Excel), SPC charting (X-bar/R, Cp/Cpk), raw spectral log export, and electronic signature support for regulated environments. All data files include embedded metadata: operator ID, timestamp, instrument serial number, calibration date, and environmental ambient temperature/humidity (optional external sensor input).
Applications
- Quality control of optical films in display manufacturing (OLED encapsulation, anti-glare layers).
- Regulatory compliance testing for medical device packaging (ISO 11607–2:2019 barrier transparency verification).
- R&D evaluation of nanoparticle dispersion stability in liquid formulations (e.g., colloidal suspensions, injectables).
- Process validation of extrusion and coating lines for polymer optics and automotive glazing.
- Supplier qualification per automotive OEM standards (e.g., GMW14872, Ford WSS-M99P1111-A).
- Academic research in photonics, material science, and food chemistry requiring traceable haze/transmittance metrics.
FAQ
What standards does the SGW-810 comply with?
It conforms to ASTM D1003–22, GB/T 2410–2008, JIS K7105:1981, and supports method adaptation for ISO 14782:2015 (plastics—determination of haze) and USP (clarity of liquids).
Can the instrument measure colored or UV-absorbing materials?
Yes—provided the sample transmits within the visible spectrum (380–780 nm); for UV-sensitive applications, optional UV-blocking filters are available upon request.
Is third-party calibration certification available?
Yes—GBPI offers NIST-traceable calibration certificates (ISO/IEC 17025 accredited by CNAS) with uncertainty budgets and annual recalibration services.
How is measurement repeatability verified?
Per ASTM D1003 Section 10.2: ten consecutive readings on certified reference standards yield ≤0.05% RSD for haze ≤0.5% and ≤0.1% RSD for haze >0.5%, validated during factory acceptance testing.
Does the system support networked lab integration?
Via optional Ethernet module (SGW-810-E), enabling DICOM-compatible data streaming and LIMS connectivity through HL7 or ASTM E1384 interfaces.
