CHN SPEC DH-12 Haze Meter (ISO+ASTM Standard; 21mm/15mm)

CHN SPEC DH-12 Haze Meter (ISO+ASTM Standard; 21mm/15mm)

The CHN SPEC DH-12 Haze Meter (Haze and Transmittance Meter) is a high-end optical measurement device designed to completely solve the problem of differing testing standards between various regions and markets. Instead of having to invest in multiple separate devices, the DH-12 allows research and development (R&D) laboratories and quality control (QC) departments to accurately analyze Haze and Transmittance on a single platform, ensuring outgoing products meet all global regulations.

Outstanding Features

Dual integration of ISO and ASTM standards: This is the core value of the DH-12. The device is designed with a special optical system to measure and provide parallel results according to both ASTM D1003 (commonly used in the US/Asia) and ISO 13468 / ISO 14782 (commonly used in Europe) standards. This helps businesses confidently export products to any market without worrying about testing data discrepancies.

• Flexible dual measurement apertures (21mm and 15mm): The device comes with 2 easily interchangeable apertures:
• 21mm Aperture: Standard size, optimal for measuring wide, flat material panels to collect the most accurate overall data.
• 15mm Aperture: Suitable for measuring smaller details, optical lenses, or areas with limited surface area that the large aperture cannot closely contact.

Smart open measurement chamber design: The measurement area features an open design (Open sample compartment), allowing users to directly insert large glass panels, long rolls of film, or LCD screens for measurement without wasting time or risking damaging the samples by cutting them.

Comprehensive measurement range (0 – 100%): The device possesses a complete measurement range from 0% to 100% for both haze and light transmittance, perfectly measuring all states from ultra-clear glass to translucent plastic sheets.

Independent operation with touch screen: The DH-12 is equipped with an intuitive color touch screen. The user-friendly interface helps operators easily perform measurements, view data, switch standards, and set tolerance alerts (Pass/Fail) directly without necessarily connecting to a computer.

Practical Applications

With its ability to meet multiple standards and flexible apertures, the CHN SPEC DH-12 is a top choice for:

• Plastics and Packaging Industry: Evaluating the transparency and haze of packaging plastic films (PE, PP), PET films, polycarbonate sheets, and acrylic (PMMA).
• Architectural & Automotive Glass Manufacturing: Testing the optical quality of windshields, laminated safety glass, reflective coated glass, and window tint films.
• Display & Optoelectronics Industry: Inspecting the haze of touch screen protective glass, polarizing films, and backlight panels used in LCD/OLED screens.
• Optical Equipment: Measuring the light transmittance of lenses, microscopes, and sunglasses.
