Overview
The 3nh YH1200 Transmittance and Haze Meter is an automated optical measurement instrument engineered for high-precision, traceable quantification of total transmittance and haze in transparent and translucent materials. It operates on the principle of integrating sphere photometry with dual-mode illumination geometry—compliant with both ASTM D1003 (non-compensated method) and ISO 13468 (compensated method)—enabling accurate separation of direct and diffuse transmittance components. The instrument employs a 154 mm diameter integrating sphere with a 400–700 nm broadband LED light source, spectrally matched to the CIE 1931 2° standard observer function (V(λ)) via a PD (photodiode) array detector. This spectral alignment ensures metrological consistency with international photometric conventions and supports compliance-critical applications in regulated manufacturing environments.
Key Features
- Dual-standard compliance: Simultaneously supports ASTM D1003/D1044 (non-compensated), ISO 13468 (compensated), ISO 14782, JIS K7105/K7361/K7136, GB/T 2410, and JJF 1303–2011—enabling global test protocol harmonization.
- Dynamic environmental compensation: Integrated temperature sensor and independent source monitoring continuously track thermal drift and LED output stability, minimizing measurement variance across ambient fluctuations (0–40 °C operating range).
- Modular aperture system: Interchangeable measurement ports (Φ20 mm, Φ15 mm, Φ8 mm, Φ4 mm) allow optimization for sample thickness (up to 170 mm) and geometric constraints without recalibration.
- Open-sample architecture: Vertically or horizontally oriented placement accommodates rigid panels, flexible films, liquid cuvettes, and curved substrates—eliminating fixture-induced stress or alignment error.
- Real-time validation interface: 7-inch capacitive TFT touchscreen with intuitive workflow navigation, pass/fail threshold overlay, and on-device result verification prior to export.
Sample Compatibility & Compliance
The YH1200 is validated for use across polymer films, tempered glass, OLED/LCD cover lenses, pharmaceutical vials, medical packaging, and coated optical substrates. Its open measurement zone enables non-contact assessment of heat-sensitive or dimensionally unstable specimens. All optical path components—including the integrating sphere coating, detector spectral response, and LED spectral power distribution—are traceably aligned to CIE 15:2018 and NIST-traceable reference standards. Instrument performance meets the repeatability and inter-instrument agreement requirements defined in JJF 1303–2011 (Chinese national verification regulation for haze meters) and ISO/IEC 17025–2017 clause 6.4.3 for measurement uncertainty estimation. Data integrity safeguards include timestamped audit trails, user-access-level permissions, and optional 21 CFR Part 11–compliant software modules for GMP/GLP-regulated laboratories.
Software & Data Management
The bundled Quality Management Software (QMS) provides full PC-based control, statistical process monitoring (SPC), and report generation compliant with ISO 9001 documentation requirements. Raw data—including transmittance (%TISO, %TASTM), haze (%H), measurement date/time, operator ID, aperture used, and environmental conditions—is stored in encrypted CSV and XML formats. Batch comparison tools support delta-haze (ΔH) and delta-transmittance (ΔT) trending across material lots or production shifts. Export templates are configurable for integration with LIMS, MES, and ERP systems via USB or serial interface. Firmware updates and calibration certificate management are handled through secure online portal access—not embedded web servers or cloud dependencies.
Applications
The YH1200 serves as a primary quality assurance tool in optics manufacturing (e.g., AR-coated glass, anti-fog polycarbonate), packaging R&D (PET trays, blister foil laminates), display component validation (touch panel overlays, encapsulant films), and pharmaceutical container testing (IV bag clarity, ampoule homogeneity). In R&D settings, its rapid 1.5 s measurement cycle supports high-throughput screening of additive formulations (e.g., nucleating agents, UV stabilizers) and processing parameters (extrusion temperature, annealing time). Its ability to distinguish between surface scattering (e.g., mold release residue) and bulk scattering (e.g., phase-separated domains) aids root-cause analysis in failure investigations per ASTM E2925.
FAQ
What standards does the YH1200 explicitly support for haze and transmittance measurement?
ASTM D1003 (non-compensated), ASTM D1044, ISO 13468 (compensated), ISO 14782, JIS K7105, JIS K7361, JIS K7136, GB/T 2410, and JJF 1303–2011.
Is the instrument suitable for measuring curved or thick samples?
Yes—the open measurement chamber accommodates samples up to 170 mm in thickness and permits vertical/horizontal orientation for convex or concave geometries without mechanical clamping.
How is measurement traceability maintained?
Through factory calibration against NIST-traceable haze reference plaques and spectral irradiance standards; each unit ships with a calibration certificate valid for 12 months under normal use conditions.
Can raw spectral data be exported for third-party analysis?
No—the YH1200 reports only integrated photometric values (total transmittance, haze); it does not output spectral reflectance/transmittance curves.
What is the expected lifetime of the LED light source?
Rated for ≥3 million measurements or 5 years of typical laboratory use (based on 2,000 cycles/day), with output stability monitored in real time and compensated algorithmically.
