Whiteness meter AMITTARI AWM-216 Flat surface object or powder whiteness measurement

AWM-216 Whiteness Meter overview

AMITTARI AWM-216 Whiteness Meter is a horizontal digital display Whiteness Meter with a white shell, which is used to directly measure the whiteness value of flat surface objects or powders. The measuring range of AWM-216 Whiteness Meter is 0~120, The resolution is 0.1. AWM-216 Whiteness Meter adopts LED 457nm light source and simple optical path design to accurately and quantitatively reflect the whiteness value after fluorescent whitening, which meets various national standards. The measuring aperture is rectangular and the size is 18x11mm.

AWM-216 Features

1. Adopt high-quality imported components and components, with good reliability.

2. Reasonable and concise optical path design, using a modified color filter system, can quantitatively reflect the whiteness value after fluorescent whitening.

3. The Whiteness Meter is composed of light source, optical system, detection system, data processing and display system. The whiteness calculation formula of AWM-216 Whiteness Meter is blue light whiteness R457.

4. Define the whiteness value of a perfect diffuse reflector whose diffuse reflectance is 1 in the visible spectrum range is 100, and the whiteness value of a black surface with a spectral reflectance factor of 0 is 0.

5. There is no need to warm up after starting up, and the measurement can be carried out after simple calibration, which is easy to operate

6. With data storage function, it can store 254 sets of data.

7. AWM-216 uses USB and RS-232C data line output to connect with PC for data collection.

8. In addition, there is an option for Bluetooth data output.

Principle

The measurement and reception of AWM-216 Whiteness Meter adopts the principle of photoelectric effect. The radiance energy value of the diffuse reflection of the sample surface is received by the photocell, amplified by a high-precision automatic zero-stabilizing operational amplifier, and then input to the calibration circuit for energy value calibration, and then the digital display directly displays the whiteness value of the sample.
