3nh YH1210 High-Precision Horizontal Haze Meter

Overview

The 3nh YH1210 High-Precision Horizontal Haze Meter is a laboratory-grade optical instrument engineered for accurate, repeatable measurement of haze and total transmittance in transparent and translucent materials. It operates on the principle of collimated transmission geometry (0/D illumination—normal incidence with diffuse collection), conforming to internationally recognized photometric standards including ASTM D1003 (non-compensated method), ISO 13468 (compensated method), ISO 14782, JIS K7105, and GB/T 2410. The instrument integrates a precision-matched PD (photodiode) array detector calibrated to the CIE standard photopic luminosity function V(λ) for 2° observer, ensuring spectral response fidelity across the visible spectrum (400–700 nm). Its horizontal benchtop configuration—combined with an open sample chamber—enables flexible positioning of specimens in both vertical and horizontal orientations, accommodating irregular geometries, rigid plates, flexible films, and curved substrates up to 105 mm in thickness.

Key Features

• Compliant dual-standard operation: Supports both ASTM D1003 (non-compensated) and ISO 13468 (compensated) methodologies within a single platform, eliminating the need for multiple instruments across regulatory environments.
• Integrated thermal and optical monitoring: Independent light-source and ambient temperature sensors continuously track drift in LED output and environmental conditions, enabling real-time compensation and maintaining metrological integrity over extended measurement sessions.
• Modular aperture system: Interchangeable apertures (Φ4 mm, Φ8 mm, Φ15 mm, Φ20 mm) allow optimization of signal-to-noise ratio and spatial resolution per application—critical for thin films, coated lenses, or micro-patterned displays.
• High-fidelity optical architecture: 154 mm diameter integrating sphere with spectrally stable 400–700 nm LED illumination ensures uniform irradiance distribution and minimizes stray-light error; achieves haze repeatability < 0.05 (Φ20 mm) and transmittance repeatability ±0.5% under controlled pre-conditioning.
• Industrial-grade human interface: 7-inch capacitive touchscreen display with multilingual support (English, Simplified/Traditional Chinese); intuitive workflow navigation, on-device pass/fail evaluation, and real-time statistical feedback (mean, SD, min/max).

Sample Compatibility & Compliance

The YH1210 accommodates flat, curved, rigid, and flexible specimens—including glass panes, PET/PC/PVC films, acrylic sheets, OLED encapsulation layers, pharmaceutical blister packaging, and automotive glazing—without mechanical clamping or vacuum fixation. Its open-access design supports manual alignment and rapid throughput in QC laboratories operating under GLP or ISO/IEC 17025 frameworks. Regulatory compliance extends to ASTM E308 (colorimetric computation), CIE 15:2018 (colorimetry fundamentals), JJF 1303–2011 (Chinese national verification regulation for haze meters), and JIS K7361 (plastic film transmittance). While not inherently 21 CFR Part 11 compliant, audit-trail-ready data export via USB enables integration into validated LIMS or QMS platforms supporting electronic records and signature requirements.

Software & Data Management

The included PC-based Quality Management Software provides traceable, version-controlled analysis of haze and transmittance datasets. Functions include batch calibration validation, inter-instrument comparison (with built-in inter-unit deviation reporting ≤0.4 for Φ20 mm), statistical process control (SPC) charting, customizable report generation (PDF/Excel), and historical trend analysis across user-defined timeframes. Raw measurement logs—including timestamp, operator ID, aperture selection, reference calibration status, and environmental sensor readings—are stored locally and exportable for internal audits or regulatory submissions. Data structures adhere to ASTM E1447-compliant metadata tagging for long-term archival integrity.

Applications

The YH1210 serves as a primary metrology tool in R&D and production QA/QC workflows across regulated and industrial sectors. In display manufacturing, it verifies anti-glare coating uniformity and cover-glass clarity prior to lamination. In medical packaging, it quantifies haze shifts induced by sterilization cycles or moisture ingress in Tyvek® or thermoformed trays. Polymer compounders use it to correlate melt-index variations with bulk optical homogeneity in extruded sheets. Automotive suppliers apply it to assess UV-stabilizer efficacy in polycarbonate headlamp lenses. Additionally, it supports ASTM D1003-based material qualification in aerospace transparent composites and ISO 13468-compliant certification of optical-grade PMMA used in lighting diffusers and signage.

FAQ

What standards does the YH1210 support for haze and transmittance measurement?
ASTM D1003 (non-compensated), ISO 13468 (compensated), ISO 14782, JIS K7105, JIS K7361, GB/T 2410, and JJF 1303–2011.
Can the YH1210 measure curved or thick samples?
Yes—the open horizontal chamber accepts specimens up to 105 mm thick and accommodates gentle curvature when positioned vertically or horizontally.
Is the instrument suitable for GMP/GLP-regulated environments?
It supports traceability through timestamped data export, calibration logging, and SPC-capable software; however, full 21 CFR Part 11 compliance requires integration with validated third-party LIMS infrastructure.
How often must the instrument be recalibrated?
Annual verification against NIST-traceable haze standards is recommended; daily zero calibration using the supplied 0% black trap and periodic reference checks with certified haze tiles (e.g., 10%, 30%, 60%) ensure ongoing accuracy.
Does the YH1210 support automated data transfer to enterprise systems?
Yes—via USB interface, raw measurement files (.csv/.txt) and structured reports can be ingested directly into LabVantage, Thermo Fisher SampleManager, or custom MES platforms using standard file-watch protocols.
