KR-2903 Dual-Standard Transmittance & Haze Analyzer
ISO 13468 ASTM D1003 Color Haze Tester
The RT-2903 Transmittance Haze Meter complies with ISO&ASTM dual standards and has dual apertures (21mm/7mm). It is suitable for one-stop measurement of haze and transmittance of transparent and semitransparent materials such as plastics, films, glass, LCD panels, touch screens, etc.
Product Details：
Product Introduction
The KR-2903 optical haze testing device is a high-precision bench instrument dedicated to simultaneous testing of luminous transmittance and haze value for transparent & semi-transparent flat materials. It fully complies with dual international test protocols ASTM D1003 and ISO 13468, supporting three standard CIE light sources (D65, A, C) to match global inspection requirements.
Adopting D/0 diffuse illumination optical structure and high-stability full-spectrum LED light source, this analyzer completes one-click testing within 1.5 seconds without lengthy preheating steps. The open-frame test station supports both vertical and horizontal sample placement, compatible with thin films, rigid glass panels, touch displays and even liquid cuvette specimens. It is widely deployed in optical glass factories, flexible film manufacturers, electronic screen R&D labs, food packaging enterprises and third-party optical certification institutions for batch optical performance inspection.
Core Competitive Advantages
- Instant Startup, Ultra-Fast Testing Response
No mandatory preheating cycle required after power-on; one-touch calibration function eliminates complex manual correction operations. Single sample test finishes in only 1.5s, drastically boosting daily QC batch testing efficiency compared with traditional haze meters that need 5–10 minutes preheat.
2.Long-Life Constant LED Illumination Module
400–700nm integrated full-spectrum LED light source features 10-year service life without frequent lamp replacement. Stable luminous intensity effectively reduces long-term test drift, ensuring consistent repeatability even after thousands of continuous measurement cycles.3.Dual Aperture Flexible Sample Matching Design
Standard 21mm large measuring aperture for large-area sheets, interchangeable small apertures (7/5/4mm) for tiny precision components like lens fragments. The open unrestricted test platform accepts oversized panels without cutting samples, lowering specimen preparation workload.4.Dual Test Modes For Multi-Type Specimens
Supports vertical placement for flat films, glass and screen substrates; horizontal laying for liquid samples, plastic bottles and curved light diffusers. Thickness tolerance up to 170mm covers most industrial transparent material specifications.5.Android Touch Intelligent Data System
7-inch capacitive color touch HMI stores all test records with timestamp; built-in USB data export function connects desktop computers for automatic report generation. The system auto-judges PASS/FAIL results against preset optical thresholds for intuitive quality screening.6.Superior Long-Term Measurement Repeatability
Equipped high-sensitivity PD array sensor complying with CIE 2° visual response curve. After standard calibration, haze test repeatability error is controlled below 0.15, far outperforming ordinary haze testers with severe data fluctuation during continuous operation.

Standard Complete Test Operation Workflow
- Power-On Automatic Self-Check
Switch on the analyzer, the touchscreen runs built-in optical self-calibration automatically without extra adjustment; confirm no error prompts before sample testing.
- Specimen Placement Selection
Choose vertical placement for solid sheets/films, or horizontal laying for liquid cuvettes and curved plastic housings, center the sample within the measuring aperture.
- One-Click Quick Measurement
Tap the test button on touch panel, the instrument automatically collects scattered & parallel light data and instantly displays haze and transmittance dual values on screen.
- Data Storage & Report Export
Save qualified test data to internal memory; connect USB cable to PC software to export batch test tables with complete specimen information for filing.
- Continuous Batch Testing
Replace new samples repeatedly without re-calibration between groups; the stable light source guarantees uniform data for dozens of consecutive test pieces.
- Post-Test Daily Maintenance
Wipe the optical window with dust-free cloth to avoid dust accumulation blocking light path; cover the matched dust cover when the machine is not in use.
Applicable Materials & Industrial Application Scenarios
Glass & Optical Display Industry
AG anti-glare glass, tempered phone panels, eyeglass lenses, touch screen cover plates, automotive windshield glass; detect light scattering haze for visual experience optimization.
