Hue meter/Brightness meter

The 527 color tone/brightness meter is specifically designed for measuring the brightness of blue, uncured coatings (such as adhesive pigments applied on flat surfaces), in order to determine their color intensity according to ASTM D 3265 and ASTM D 2745. In addition to this special application, the instrument can also serve as a standard reflectance photometer to measure the brightness of solid materials such as carbon black, coatings, paper, and plastics according to ASTM E 97 standards.optionalCD/RS232 analog output interface.

the instrumentPowered by a pedestal and display unit(with digital display, range 0-199.99) and a portable color tone probe.

Color tone probe combined45°0°World standard measurement angle, withCType of lighting source. The spectral response of the photosensitive cell transmitted by the light source is corrected by a specially selected Ya filter. So that the measured values conform toCIE-2°Standard brightness sensitivity. A lens system that has been adjusted and optimized is part of the light transmission and sensing optical system, used to ensure uniform illumination of the sample surface and receive reflected light according to the prescribed method. So the measurement results have high reproducibility, no offset, and meet the regulatory requirements

The photoelectric system of the measuring head is insensitive to external interference due to the internal combination of amplifiers. The amplification factor can be set to a wide range, so the measurement range of the instrument can be adjusted according to actual needs to obtain * results.

Two horizontal support plates8mmWide, located at a distance from the lower part of the head80mmMove the probe away from the template to make it possible to measure the lake shaped coating: the horizontal plate prevents sample damage and probe contamination, and the gap between the probe and the sample is0.5mmSo it can measure approximately without the influence of external light400mmThe color tone of the wet film coating.
