JianHu JH-Series Portable Film Transmittance and Haze Tester

Overview

The JianHu JH-Series Portable Film Transmittance and Haze Tester is an optical measurement instrument engineered for precision quantification of visible light transmittance (T%) and haze (%) in thin polymeric films, coated substrates, display cover glasses, solar encapsulants, and other optically transparent or semi-transparent planar materials. It operates on the principle of standardized collimated beam transmission spectroscopy in accordance with ISO 13468-1 (plastics — determination of transmittance of single-layer materials) and ISO 14782 (determination of haze for transparent plastics), utilizing a stabilized tungsten-halogen light source (380–780 nm spectral range), dual-detector photometric architecture, and calibrated integrating sphere geometry. Unlike benchtop spectrophotometers requiring sample alignment and environmental stabilization, the JH-Series integrates optical path optimization, temperature-compensated photodiodes, and real-time signal normalization to deliver repeatable measurements under variable ambient lighting conditions—making it suitable for inline QC, field verification, and R&D lab environments where portability and operational robustness are critical.

Key Features

• Integrated intelligent auto-calibration system with NIST-traceable reference standards for zero and 100% transmittance/haze validation prior to each measurement sequence
• Compact, handheld form factor (≤1.2 kg) with ergonomic grip, rechargeable Li-ion battery (≥8 hours continuous operation), and IP54-rated enclosure for dust/moisture resistance
• High-resolution color LCD touchscreen (4.3″, 480×272) with multilingual UI (English, Chinese, Spanish, German), intuitive icon-driven workflow navigation, and on-device data review
• Dual-mode measurement capability: simultaneous transmittance (T%) and haze (%) output per ASTM D1003 and ISO 14782 protocols; optional spectral transmittance mode (380–780 nm, 10 nm resolution) available via firmware upgrade
• Internal memory stores up to 10,000 test records with timestamp, operator ID, sample ID, and environmental metadata (ambient temperature & relative humidity)
• USB-C and Bluetooth 5.0 connectivity for direct data export to PC or mobile devices; compatible with JianHu LabLink™ desktop software for advanced statistical analysis and report generation

Sample Compatibility & Compliance

The JH-Series accommodates flat, rigid, or flexible film specimens up to 0.5 mm thickness and ≥25 mm × 25 mm surface area. It supports standard 10 mm, 25 mm, and 50 mm aperture configurations (interchangeable front masks). Samples must be free of gross surface contamination, scratches, or non-uniform curvature exceeding ±0.1 mm deviation over 10 mm baseline. The instrument complies with electromagnetic compatibility (EMC) requirements per IEC 61326-1 and safety standards per IEC 61010-1. Measurement traceability aligns with ISO/IEC 17025 principles when used within validated laboratory procedures. Data integrity features include electronic audit trail (user login, calibration logs, measurement history), password-protected configuration access, and optional 21 CFR Part 11-compliant software module for regulated pharmaceutical and medical device manufacturing environments.

Software & Data Management

JianHu LabLink™ software (Windows/macOS) enables full instrument control, batch reporting, SPC charting (X-bar/R, Cp/Cpk), and export to CSV, PDF, or XML formats. Raw photometric data—including detector voltage profiles, spectral integrals, and haze calculation intermediates—is retained for forensic review. The software supports GLP/GMP documentation workflows, including electronic signatures, revision-controlled test templates, and automated certificate-of-conformance generation. Cloud synchronization (via optional JianHu CloudSync™ subscription) provides secure, encrypted backup and cross-site data aggregation for multi-facility quality systems. All firmware updates are digitally signed and delivered via authenticated OTA channel.

Applications

• Quality assurance of PET, PC, PMMA, and TPU films used in touch panel laminates, OLED encapsulation, and AR/VR optics
• In-process verification of anti-reflective, hard-coat, and hydrophobic coatings on display glass and automotive HUD substrates
• Material qualification for photovoltaic encapsulants (EVA, POE) and backsheet films under accelerated aging protocols
• R&D screening of nanostructured transparent conductive films (ITO, AgNW, graphene oxide) during formulation development
• Third-party testing labs performing accredited transmittance/haze assessments per ISO, ASTM, or customer-specific specifications
• Educational laboratories teaching optical metrology fundamentals and polymer characterization techniques

FAQ

What standards does the JH-Series tester comply with?
It adheres to ISO 13468-1, ISO 14782, ASTM D1003, and JIS K 7105 for transmittance and haze measurement methodology.
Can the instrument measure curved or textured surfaces?
No—it requires optically flat, planar samples; curvature or surface roughness beyond Ra < 0.05 µm will introduce systematic error.
Is calibration traceable to national metrology institutes?
Yes—factory calibration uses NIST-traceable neutral density filters and haze standards certified by CNAS-accredited labs.
Does the device support GLP/GMP audit requirements?
With LabLink™ software and optional Part 11 module enabled, it provides full electronic record retention, user access controls, and change history logging.
How often is recalibration recommended?
Annual recalibration is advised; however, daily intelligent self-check and reference standard verification ensure ongoing accuracy between formal calibrations.
