Versatile Sphere Spectrophotometer for Portable and Lab-based Color Measurement
The Lovibond™ TRA 520 is a highly adaptable sphere spectrophotometer engineered for both handheld and benchtop use. Offering switchable aperture sizes, advanced colorimetric indices, and a camera-based sample locator, it ensures exceptional accuracy and flexibility for quality control in coatings, plastics, textiles, and household goods. Delivered with OnShade software, it allows for in-depth analysis and effortless reporting.
Key Features
- Dual-Mode Functionality: Use as a handheld or benchtop unit
- Wide Sample Compatibility: Measures powders, liquids, gels, pastes, granules, solids, and fluorescent materials
- Adjustable Apertures: Dual aperture system (10 mm/8 mm and 5 mm/4 mm)
- Camera Viewfinder: Ensures exact sample positioning to avoid geometric metamerism
- SCI & SCE Modes: Includes specular included and excluded components for reflectance geometry
- UV In/Out Capability: Measures fluorescent materials with controlled UV lighting
- Extensive Data Display: Colorimetric values, difference graphs, pass/fail, spectral curves, chromaticity
- Long Battery Life: 5000 measurements or up to 8 hours of use
Applications
- Coatings (paint, surface finishes)
- Plastics (colored resin, molded parts)
- Textiles (dyes, fibers, fabrics)
- Household Products (cleaners, packaging, personal care items)
- Powders, Gels, Pastes, Granules (multi-form sample compatibility)
