Aeros spectrophotometer

Aeros spectrophotometer:

Non-contact color measurement

The Aeros® spectrophotometer from HunterLab has integrated quality control software and averages over a large surface area to measure all inhomogeneous samples with non-uniform structure – non-contact, precise and resource-efficient!

Your advantages at a glance

The perfect solution for laboratory & production

  • Non-contact measurement

    The sensor detects the sample without contact, without having to measure through plastic or glass.

  • Large surface area

    The rotating sample plate captures over 170 cm2 of the sample in 35 measurements in 7 seconds.
  • Integrated QC software

    The EasyMatch QC Essentials quality control software is integrated into the device and provides all the required color indices and metrics.
  • Intelligent height adjustment

    The distance sensor automatically compensates for height differences in irregular samples.
  • Smart user interface

    Your measurement results can be easily transferred to existing LIMS or SPC systems.
  • Uncomplicated & precise

    Simple "one touch" measurement reduces training time, optimizes the workflow and increases your productivity.

Smart color measurement system for various industries

For inhomogeneous products, bulk goods and small parts, the Aeros® is the best choice for color measurement with maximum connectivity, integrated QC software and robust design. The Aeros® is used successfully in various industries, including for the following use cases:

Snack-Food, Nüsse, Chips, Süßwaren

Snack food, nuts, potato chips, confectionery

The large sample trays of the Aeros are ideal for snack food products such as flips, potato chips, nuts, as well as cookies and fruit gums.

Fast spectral analysis in CIE Lab color values and many other measurement data with the Aeros all-in-one color measurement system.

How the Aeros® spectrophotometer works

With its automatic height adjustment and the ability to measure and average at 7 readings per second over a large surface area, the modern Aeros® spectrophotometer enables you to precisely measure even large, irregularly shaped samples of all kinds, such as chunky foods like baked goods, nuts or pasta, as well as various raw materials and products from the plastics industry in granulate form.

The Aeros® spectrophotometer from HunterLab simulates human color perception in accordance with the CIE standard valence system in a matter of seconds in an absolutely reliable, safe and reproducible manner.
