Reflectance Meter Product Information
I. Product Description
This reflectance meter can measure the transmittance of coatings, oils, films, plastics, and organic materials, while simultaneously measuring the reflectance of solid surfaces (such as cinema screens). It is widely used for quality inspection and standardized control in industries including coatings, pigments, inks, plastics, printing and dyeing, leather, and film projection.
II. Product Features
Complies with international standards ISO 3906-1980 (E), ISO 3905, and ISO 2814, and meets the relevant specifications of Chinese national standards GB/T 13452.3-92, GB 9270-88, and GB 5211.17-88;
System Configuration: Main unit, 1 black standard plate, 1 white standard plate, 1 black working ceramic plate, and 1 white working ceramic plate;
Testing Principle: Light reflected from the sample strikes a photodiode to generate an electrical signal, which is amplified by a DC amplifier and displayed as a numerical value;
Data Output: Standard USB interface for computer connection; optional Bluetooth wireless data transmission.
