PCE WNM 100 Whiteness Meter (0~120)

PCE WNM 100 Whiteness Meter (0~120)

The PCE WNM 100 whiteness meter is an optimal solution designed to analyze and evaluate whiteness index based on the blue light reflectance measurement method according to the ISO R457 (ISO 2469) standard. The device operates with a 457 nm wavelength LED light source combined with standard 45/0 photometric geometry, helping to quickly and accurately check whiteness indicators without damaging the sample.

Outstanding Features

Comprehensive optical measurement system: The device is equipped with a specialized 457 nm LED light source along with an optical system featuring a wide measurement area (18 x 11 mm), ensuring accurate collection and analysis of light reflectance on various flat surfaces or powder forms.

Powerful parameter testing performance: Measuring in the range from 0 to 120 with high resolution (0.1), superior repeatability and stability, strictly complying with the R457 blue light whiteness calculation method.

Intelligent operation and connection system:

• Friendly interface and fast calibration: Intuitive LCD screen display, accompanied by a white reference plate for easy calibration before measuring.
• Data memory and PC connection: Allows direct storage of up to 245 measurement values on the device, supporting a serial communication port to connect to a computer for live data logging.

Manufacturing materials and durable structure: Compact handheld design, light weight (approx. 305 g), sturdy structure to facilitate convenient operations in laboratories or production lines.

Energy-optimized operation mechanism: Uses a high-capacity Lithium-ion rechargeable battery, ensuring stable and durable operating time throughout testing procedures.

Practical Applications

Thanks to its precise whiteness control capability according to international standards, the PCE WNM 100 is widely applied in many industries:

• Paper & Packaging Industry: Testing brightness and whiteness of paper, cardboard, and pulp during production.
• Plastics & Construction Materials Industry: Evaluating whiteness of plastic batches, skim coats, cement, ceramics, and finishing materials.
• Textile & Chemical Industry: Checking whiteness of fabrics, knitted goods, detergents, or fine powder raw materials.
