Haze Meter

I. Product Introduction

The haze meter is an instrument used to determine the optical properties of transparent and translucent parallel-plane materials and plastic films. When a beam of parallel light enters a medium (such as transparent plastic), due to the inhomogeneity of the optical properties of the material, surface defects, inhomogeneity of internal structure, presence of bubbles and impurities, etc., the beam changes direction (diffusion and deflection). The resulting partially disordered light is called scattered light. Internationally, the ratio of the scattered luminous flux deviating from the incident light direction after passing through the specimen to the transmitted luminous flux, expressed as a percentage, is the so-called haze. A specimen with high haze will appear more blurred.

II. Application Scope

Used for transmittance and haze measurement of colorless transparent materials.

1. Plastics industry: used to evaluate the quality of plastic films and sheets, such as the haze of polyethylene (PE) and polypropylene (PP), to ensure that their transparency and optical properties meet production requirements. Detects the appearance of plastic packaging materials such as food packaging and pharmaceutical packaging.

2. Glass manufacturing: measures the haze of architectural glass and automotive glass to judge visual clarity and optical uniformity; helps optimize glass production processes and improve product quality.

3. Coatings and paints: determines the haze of coatings formed on different substrates to evaluate their gloss and appearance; used to compare the optical properties of different formulations when developing new coatings.

4. Display industry: detects the haze of liquid crystal displays (LCD) and organic light-emitting diodes (OLED) to ensure screen display effect and visual experience.

5. Optical materials: evaluates the haze of optical lenses, prisms and other components for precise analysis of their optical performance.

6. Lighting field: measures the haze of lamp shades and diffuser plates to achieve ideal light distribution and softness.

7. Medical industry: detects the haze of transparent materials used in medical devices such as infusion tubes and protective masks; used for transparency testing of drugs.

8. Chemical industry: used to determine the transparency of liquid solutions and help control the production process.

9. Food industry: detects the quality of juice, beverages and other products.

10. Environmental protection: monitors water quality, etc.

IV. Product Features

1. Efficient, accurate and fast determination: relying on a standardized operating process and precisely controlled test conditions, detection is fast and efficient, ensuring consistency and accuracy of results. A human-eye response detector is used, whose spectral response curve almost completely matches the visual function Y/V(λ), capable of simulating and quantifying human eye observation.

2. Simple operation and high degree of automation: uses an LED light source simulating the CIE standard illuminant, with a longer life and immediate use without warm-up.

3. Excellent safety performance: equipped with a 12 V safety voltage adapter; the whole machine operates at low power with little heat generation, safe and reliable.

4. Convenient measurement and wide sample adaptability: an open measurement area supports both vertical and horizontal test postures, easily adapting to various sample forms. The standard 0/d optical structure makes test data more accurate and avoids surface reflection interference. It simultaneously meets the three major haze standards GB/T 2410, ASTM D 1003/1004 and ISO 13468/14782, with strong compatibility.

5. Ultra-long life and precise measurement: LED light source life up to 5 years or 5 million measurements, durable. Resolution up to 0.01 and repeatability accuracy of 0.05 ensure accurate and reliable measurement data.

6. Massive storage and convenient operation: a single unit can store 20,000 sets of test data, meeting large-volume inspection needs. Equipped with a capacitive touchscreen for smooth and sensitive operation; a 7-inch IPS full-view display with clear and transparent display. External start measurement button for more convenient operation.

7. Intelligent networking and system upgrade: supports WiFi networking, can automatically calibrate instrument timing and supports remote system upgrade for easy device performance optimization.

8. Permission grading and data security: supports multi-level user permission management, allowing creation of multiple users and assignment of different operation permissions to each, facilitating experimental traceability and data security control.

9. Data display and export: the data display interface can compare multiple samples simultaneously, making differences between samples clear at a glance. Equipped with a USB interface to support comprehensive data export for subsequent analysis and management.
