Portable Spectrophotometers

A portable spectrophotometer is an instrument used to measure and analyze color by capturing how a material reflects or transmits light across different wavelengths. Unlike visual color inspection, which can vary from person to person, spectrophotometers provide objective, repeatable, and highly accurate color data, making them essential tools for modern color quality control.

Spectrophotometers are widely used for color measurement across industries such as plastics, paints and coatings, printing and packaging, textiles, automotive etc. They play a critical role in color formulation, batch-to-batch color consistency, quality inspection, and process control, ensuring that colors remain uniform and meet required standards throughout production.

For color measurement, 3nh offers a diverse range of models of portable spectrophotometers that vary in technical specifications like geometry, sphere size, color spaces, aperture, repeatability, storage etc. to meet the different color measuring needs and requirements of the users. Some of the key specs are:

Geometry (d/8 and 45/0)

These spectrophotometers has geometry options such as 45/0 (45-degree illumination and 0-degree viewing) or d/8 (diffuse/8-degree), accommodating specific measurement needs.

Aperture

Each Spectrophotometer model has different aperture sizes ranging from 4mm to 20mm, catering to the requirements of different sample sizes and surface types.

Repeatability

Each model has distinct levels of repeatability, ensuring consistent and reliable results over multiple measurements.

Color Spaces

These spectrophotometers can measure various color spaces with precision and accuracy. Whether it’s assessing colors in the CIE LAB, XYZ, Yxy, LCh, RGB or other color spaces, their spectrophotometers offer reliable and accurate measurements.

Illuminants

Supports multiple illuminants such as D65 (daylight), D50, A (incandescent), C, and F-series light sources (F2, F7, F11, F12) for accurate color evaluation under different lighting conditions.
