Whiteness Meter AWM-216

Product Description

AMITTARI l Whiteness Meter is mainly used to directly measure the whiteness value of object or powde r with flat surface. It can be widely used in whiteness measurement of textile printing and dyeing, paint, chemical building materials, paper board, plastic products, white cement, ceramics, enamel, t alc powder, starch, flour, salt, detergent, cosmetics and other substances.

The instrument pass strict inspection and testing, conforms to the JJG 512-2002 Whiteness Meter Veri fication Regulation. Also conforms to GB3978、GB3979、GB7973、GB7974、ISO2470、GB8904.2、QB1840、GB2913、GB1 3025.2、GB1543、ISO2471、GB10339、GB5950、GB12911、GB2409 and other standards

Product Features

It consists of Light Source, Optical System, Detection System,

Data Process and Display System.

Use of high quality imported components, good reliability.

The optical path design is reasonable, simple. Adopt filter system

with correction, the whiteness can be reflected quantitatively.

No preheating after starting, measurements can be taken after

simple calibration, easy to operate.

Able to memory 254 groups of measurement data.

Use USB data output and RS-232 data output to connect with PC.

Provide Bluetooth data output choice.

Operational Principle

The Illuminant of the instrument is long-life LED with 457nm, conforming to the light source require ment in the JJG 512-2002 National Metrological Whiteness Meter Verification Regulation. The measurem ent of the instrument adopts the principle of photoelectric effect. The diffuse reflectance Radiant Brightness Energy Value of the sample surface is receive by the optical cell. Then, the value is amp lified by high-precision auto zeroing operation amplifier, inputted to the calibration circuit for e nergy calibration. Then, the whiteness value of the sample is directly shown on the digital display.
