Description
Digital Whiteness Meter R457 Brightness Opacity Tester
This electronic digital brightness/whiteness/opacity tester is designed for measuring non-colored surfaces of flat objects or white powders, providing accurate visual correlation. The instrument fully complies with international standards including ISO 2469 and relevant national and industry standards.
Key Features
  • Precisely matched integral filter for optimal spectrum conditions
  • Micro-computer controlled with automatic data processing and optional printer connectivity
  • Backup power system protects data during power outages or shutdowns
  • High-efficiency switching power supply with compact design and strong anti-interference capabilities
  • Touch-type keyboard for easy data input and configuration
  • Direct LED display for immediate measurement results
  • Measures ISO brightness (R457 blue light brightness) and fluorescent brightness
  • Determines transparency (T) and brightness stimulus (V10)
  • Measures opacity (0) with high precision
Technical Specifications
  • Compliant with ISO 2469 international standard d/o lighting observation geometry
  • 150mm diameter integrating sphere with 32mm test hole diameter
  • Gloss absorber eliminates specular reflection from samples
  • R457 optical system: main peak wavelength 457nm, half-wave width 44nm
  • RY optical system matches CIE standard spectral power distribution of Y10 stimulus conditions D65/100
  • Meets JJG512-87 "White Meter" technical requirements
  • Compliant with JJG (Light) 48-90 "Reflection Photometer" specifications
Applications
  • Paper and cardboard manufacturing
  • Pulp and textile industries
  • Paint and coating quality control
