Product Introduction
The HM-HZ2 is a mid-range transmittance haze meter that bridges the gap between basic QC instruments and professional-grade optical analyzers. Its defining capability is dual-standard haze calculation — it computes haze values per both ASTM D1003 and BS ISO 14782 simultaneously, enabling laboratories to generate test reports accepted by customers in both American and international markets without switching instruments. With 0.01 resolution and 0.08 repeatability on its 21mm aperture, the HM-HZ2 delivers measurement precision that satisfies most ISO 17025 accredited laboratory requirements. For applications requiring dual aperture (21mm + 7mm) or the highest repeatability (0.05), the HM-HZ3 is the recommended upgrade. For budget-focused ASTM-only needs, see the HM-HZ1.
Applications
- Optical film and lens quality verification for export-grade products
- Automotive glass haze testing per international specifications
- Coating formulation comparison in R&D laboratories
- Medical device transparent material compliance testing
- Food packaging film inspection for multinational brands
- Display cover glass AG coating verification
Functional Performance
- Dual-standard haze calculation (ASTM + ISO) — unique at this price point
- 0.01 resolution captures subtle haze differences between production batches
- 7-inch IPS capacitive touchscreen with Chinese/English switching
- LED light source (CIE C illuminant, 380nm–780nm) — instant-on, no warm-up
- 0/d optical geometry with human-eye-response detector (CIE Y/V(λ))
- 20,000 data set storage with USB export for SPC analysis
- WiFi for remote firmware updates and automatic time calibration
- Multi-level user permissions for GLP/GMP data integrity
- Open measurement area (150mm) supporting vertical and horizontal testing
- DC 12V/3A safe operation with minimal heat generation
