HunterLab LabScan XE Flexible Colour Measurement

Measure the colour of samples of all forms, sizes and textures—the way the eye “sees” colour.

Now there’s a whole new dimension in the way you’ll look at measuring samples. The HunterLab LabScan XE spectrophotometer takes colour measurement to a new and totally different level of sophistication, with more simplicity, more automated features and more versatility than any other product available on the market today.

From powders, solids and liquids, to pellets, chips, yarn or paper, the HunterLab LabScan XE is the cutting-edge solution for a host of colour measurement applications in plastics, textiles, paint, food, paper, chemicals, pharmaceuticals and building materials.

The same colour, when seen on surfaces that differ by gloss or texture, ends up “looking” like a different colour to the human eye. HunterLab’s LabScan XE’s 0°/45° circumferential geometry incorporates a 15-station, fiber-optic ring that collects and averages reflected light from all the stations. The result is a fast, simplified measurement that automatically accounts for the effects of variations in textures, finishes or granulations.

Samples come in all sizes, shapes and forms, and now the HunterLab LabScan XE gives you the capability to measure their colour with unparalleled versatility, simplicity and accuracy. For instance, it features one of the largest illuminated areas available— 44mm—which gives you superior precision when scanning textured, non-uniform samples.

An optional automated Variable Sample Illumination (VSI) feature allows you to measure from 44mm to 3mm, for maximum flexibility in the sizes and kinds of samples you can measure. The VSI feature also gives you far more accuracy in measuring translucent solids or liquids.

  • For reflectance measurement of opaque or translucent solids, powders and liquids
  • Automated functions include standardisation, UV control and change of zoom lens for 5 illumination areas from 44m to 3mm
  • Xenon flash, double beam optics. (Lamp never needs replacing)
  • Designed for use with HunterLab’s quality control and formulation software.

HunterLab UltraScan VIS Professional Colour Measurement

The HunterLab UltraScan VIS is a high-performance colour measurement spectrophotometer that measures the full range of human colour perception in less than one second.

It can be used in production and in the laboratory for inspecting raw materials, evaluating finished product or developing methods for color analysis.

Because of its exceptional inter-instrument agreement and long term stability, you can be confident that differences between measurements are due to product color changes, not instrument variability.

The HunterLab UltraScan VIS measures both reflected and transmitted colour as well as transmission haze and meets CIE, ASTM and USP guidelines for accurate colour measurement.

HunterLab’s UltraScan VIS incorporates automated functions to make operation simple and reliable. Complete measurement procedures can be completed in a matter of seconds.
