Haze Meter LHM-A10

A haze meter is an instrument used to measure the level of haze and light transmittance in transparent and translucent materials. This is crucial in industries like plastics, films, glass, and display technologies, where the clarity of materials affects both appearance and functionality. Labtron’s haze meters help manufacturers ensure that products meet optical clarity standards. By measuring parameters like haze percentage and total transmittance, these meters provide reliable data for quality control and product development. Whether it’s a touch screen, a medical device, or packaging film, knowing how light passes through the material can make a big difference in performance and visual appeal.

Labtron haze meters, including the LHM-A10, are designed to comply with international standards such as ASTM D1003, ISO 13468, and JIS K 7105, among others. These standards are recognized globally and set guidelines for accurate and repeatable measurements. By following these, Labtron ensures that its haze meters produce results that are both precise and comparable to results from other certified labs or equipment. Compliance also means users can trust the data when making decisions related to material quality, product approvals, or regulatory documentation.

Labtron haze meters come with features that make them easy to operate, even for users with minimal training. Most models are equipped with a 7-inch touch screen and an intuitive user interface, which simplifies navigation through different settings and test procedures. The open sample bin design allows users to test a wide range of sample shapes and sizes without needing extensive preparation. Labtron also provides standard PC software for data analysis and storage, and many haze meters can store up to 20,000 test values, making it easier to manage large batches of measurements.

Labtron haze meters are designed for a wide range of industries. In the plastics and film industry, they help assess the clarity of packaging materials. In the glass and LCD panel sectors, haze meters measure optical performance and light diffusion. Medical device manufacturers use them to verify the transparency of plastic components, while the cosmetics and textile industries rely on them to control product consistency. The Labtron LHM-A10, for example, can measure not just haze but also color indices, whiteness, yellow index, and other optical properties—making it a versatile tool across different quality assurance applications.

Labtron haze meters may employ integrating spheres in some models to collect scattered light more uniformly and accurately. The integrating sphere captures all scattered light at multiple angles, creating a diffuse and complete representation of haze rather than a narrow-angle sample. This is especially useful when dealing with materials that scatter in multiple directions or have textured surfaces. Labtron uses highly reflective inner coatings in these spheres to minimize absorption and maximize uniformity. Integrating spheres allow measurements that align with ISO and ASTM standards requiring full-angle haze capture. This design is critical for high-fidelity haze assessments.
