Applications
Themeter is mainly used to directly measure the whiteness value of objects or powders with flat surfaces. Can be widely used in textile printing and dyeing, paint,
chemical building materials, paper and cardboard, plastic products, whitecement, ceramics, enamel, talc, starch, flour, salt, detergent, cosmetics and other
substances whiteness measurement.
Features
* It is composed of light source, optical system, detection system, data processing and display system. The whiteness calculation formula of this instrument is blue light whiteness R457.
* Define the whiteness value of an ideal surface with a diffuse reflectance ratio of 1 across the visible spectral range as 100,
and the whiteness of a black surface with a spectral reflectance factor of 0 as 0.
*Diffuse reflection is the reflection of light projected on a rough surface in
all directions. When a beam of parallel incident light is emitted to the rough surface, the surface will reflect the
light in all directions, so although the incoming rays are parallel to each other, because the normal direction of
each point is inconsistent, causing the reflected light to reflect irregularly in different directions, this reflection
is called "diffuse reflection" or "diffuse.Shoot ".
* USB, RS-232C data line output and PC connection, data collection.
* There is also a Bluetooth Bluetooth data output option.
