Product Description

Whiteness and Brightness Reflectance Meter Model RWB-206

Applications

This precision instrument is designed for direct measurement of whiteness values on flat surfaces of objects and powders. It finds extensive application across multiple industries including textile printing and dyeing, paints, chemical building materials, paper and cardboard, plastic products, white cement, ceramics, enamel, talc, starch, flour, salt, detergents, cosmetics, and various other materials requiring whiteness measurement.

Key Features

Integrated system comprising light source, optical system, detection system, and data processing/display
Utilizes blue light whiteness R457 calculation formula for accurate measurements
Calibrated scale: 100 for ideal surface with diffuse reflectance ratio of 1, 0 for black surface with spectral reflectance factor of 0
Advanced diffuse reflection technology for precise light measurement across rough surfaces
Compliant with multiple international standards including JJG512-2002, GB3978, GB3979, GB7973, GB7974, ISO2470, and others
Optional USB and RS-232C data output for PC connectivity and data collection
Bluetooth data output option available for wireless connectivity

Measurement Principle

The instrument operates on the photoelectric effect principle, featuring a long-life LED light source at 457nm wavelength. The system captures diffuse reflectance radiant brightness energy from sample surfaces, processes it through high-precision auto-zeroing operational amplifiers, and displays direct whiteness values with exceptional accuracy.
