In the field of material optical performance testing, transmittance and haze are key indicators for evaluating the quality of transparent and translucent materials. CHNSpec (Zhejiang) Co., Ltd., with its profound technical expertise and continuous innovation, has launched the THC-07 Transmittance and Haze Meter and THC-08 Color Haze Meter, providing comprehensive and reliable testing solutions for the quality control and R&D of plastics, glass, films, liquids, and other materials.
I. Dual Instruments, Comprehensive Optical Parameter Coverage
The THC-07 Transmittance and Haze Meter focuses on the detection of fundamental optical properties of materials. It can accurately measure haze, transmittance, clarity, and other key parameters, and display transmittance spectral curves within the wavelength range of 400–700 nm. The instrument features a dual-aperture design (21 mm / 7 mm) and an open measurement area, supporting both horizontal and vertical measurement modes, making it suitable for quality evaluation of most transparent and translucent materials.
The THC-08 Color Haze Meter is a comprehensive upgrade based on the THC-07. In addition to haze and transmittance, it integrates multiple color parameters such as color difference, turbidity, platinum-cobalt color, yellowness, and whiteness. It supports various color spaces and color difference formulas, enabling measurement of multiple color parameters such as CIELab, LCh, Luv, and XYZ, meeting users’ dual testing needs for both color and optical performance of materials.
II. Core Advantages: Technological Leadership and Operational Ease
1. Dual-Standard Support, Broad Applicability
The THC series supports both ASTM and ISO international standards, allowing compliance with different regional and industrial testing requirements without replacing accessories or using compensation ports. The instruments come with multiple built-in light source modes and observer angles, ensuring international compatibility of testing results.
2. Full-Spectrum LED Light Source for Accurate Data
Equipped with a full-spectrum LED light source and high-precision spectral sensor, the THC series ensures highly accurate and reliable measurements. The haze repeatability is ≤0.03, transmittance repeatability ≤0.03, and color difference repeatability ≤0.03 — performance comparable to leading imported brands, providing reliable assurance for quality control.
3. 7-Inch Touch Screen for Smooth Interaction
Featuring a 7-inch IPS full-view touch screen, the interface is intuitive and user-friendly, making data clearly visible at a glance. The system is easy to operate without the need for complex training, significantly reducing personnel training costs.
4. Dual-Aperture Design for Enhanced Sample Adaptability
With 21 mm and 7 mm dual measurement apertures, users can flexibly select based on sample size. Even samples as small as 7 mm can be accurately measured, meeting diverse detection needs in research and production environments.
5. Open Measurement Area for Multiple Sample Types
The innovative open measurement area design allows the instrument to be used in both horizontal and vertical orientations. Combined with a dedicated positioning bracket, it easily accommodates sheets, films, liquids, and even large-sized materials.
6. Professional PC Software for Worry-Free Data Management
Equipped with powerful PC software, the THC series can be connected to a computer via USB for online measurement, data export, and report printing. It supports long-term data tracking and analysis, helping enterprises establish a complete quality management system.
III. Professional Assurance: Metrology Certification You Can Trust
The THC series strictly adheres to national metrology standards, ensuring that parameters such as haze, transmittance, and color difference can pass testing and verification by national metrology institutes, guaranteeing authority and credibility. The products comply with multiple national and industrial standards, including:
JJF1303-2011: Calibration Specification for Haze Meters
GB/T 2410-2008: Determination of the Transmittance and Haze of Transparent Plastics
GB/T 3978-2008: Standard Illuminants and Geometric Conditions
GB/T 36142-2018: Methods for Measuring the Color and Color Difference of Architectural Glass (THC-08)
JJG595-2002: Verification Regulation for Color Difference Meters (THC-08)
