Digital Whiteness Meter 0-199 LED Blue Whiteness Paper Powder++++

Product Features & Attributes
This digital whiteness meter is used for whiteness measurement of white and near-white objects or powder surfaces, capable of quantitatively measuring whiteness after fluorescent brightening treatment. It is widely applied in textile dyeing, paints and coatings, chemical building materials, paper and paperboard, plastic products, white cement, ceramics, enamel, flour, salt, detergents, cosmetics and other whiteness measurement applications.

Working Principle: Using photoelectric conversion and analog-to-digital conversion circuitry, the reflected radiance energy from the sample surface is amplified, converted, processed and displayed as a whiteness value. The overall whiteness is blue whiteness R457, with 100 for ideal white surface (spectral reflectance ratio 1) and 0 for black surface (spectral reflectance ratio 0).

Two Specifications Available:

• Portable model: AC/DC power supply, low power consumption, compact design for field or laboratory use

• Benchtop model: AC 220V power supply for fixed laboratory use

Technical Features:

• Imported components, high efficiency/low loss switching power supply

• Low drift high-precision IC, long-life LED light source

• Optimized optical design for accurate and reliable readings

• Large screen LCD display, comfortable reading, unaffected by natural light

• Low voltage indication, auto power-off and low power circuit for extended battery life (portable model)

• Standard white plate calibration for accuracy

• Output interface for recorder connection

Technical Parameters:

• Measuring aperture: ≤15mm

• Minimum display value: 0.1

• Operating environment: 5~35℃, ≤85%RH

• Storage environment: -20~50℃, ≤90%RH

Available in different specifications: portable model (AC/DC), benchtop model (AC), and different measuring apertures (15mm, custom) to suit various industries and testing standards.

Mainly used in textile dyeing mills, paper mills, paint and coating manufacturers, chemical building material companies, plastic product factories, white cement plants, food processing companies, quality inspection institutions, research universities, and more for precise whiteness measurement.
