HunterLab Colorimetry Products and Color Measurement Solutions

When your customers expect – and demand – color consistency and accuracy, when color is a critical indicator of product quality or process control, when your reputation depends on the color quality of your product, you can trust HunterLab to provide the best, truest colorimetry products in the world.

At HunterLab, color measurement is our sole passion: we are the originator of the science, innovator of the technology, and the most widely known and respected name in the color measurement business. Color measurement is all we do, and we’ve done it for 60 years.

Color measurement solutions for any product

Whatever your product, we have the right measurement solution. Portable, bench and on-line systems are available to measure reflected and transmitted color of chemical and petroleum products in the form of powders, pellets, granules, tablets, fibers, pastes and liquids.

In addition to measuring color, our spectrophotometers are uniquely designed to also provide calculations in a number of metrics, such as APHA/PtCo/Hazen, Gardner Scale, Saybolt, ASTM D1500, yellowness / whiteness and transmission haze. Our system allows you to custom tailor your HunterLab color analyzer to meet your specific needs.

Versatile color analyzers

With the ability to measure color in reflectance and transmission, the ColorQuest XE and UltraScan PRO are extremely versatile color analyzers. They can accurately measure a large variety of sample types, ranging from liquids to powders to Pigment, among many others.

But not only are they versatile with different types of samples, these color analyzers are also perfectly developed for very small samples, such as adhesives, powders or liquids. Component parts are available for products where only the smallest amount of sample is possible because of short supply or high pricing of the product.

ColorFlex EZ spectrophotometer – rugged and affordable

Simple to operate, its combination of small footprint and sample flexibility make the ColorFlex EZ spectrophotometer a popular choice, especially considering its affordability and reputation for rugged construction.

Translucent liquids are ideally measured with a component ring and disk set, for oil or other samples where it is difficult to use glass cups, single use cups available.

Benchtop and online spectrophotometers

The LabScan XE measures many different types of samples with the largest area of view available in any benchtop spectrophotometer. One unique feature is its capability to measure translucent products, such as foil, filters and liquids. Coupled with our powerful EasyMatch QC software, it is the right instrument for many sample measurement requirements.

The SpectraTrend HT measures samples at the process line, continuous, fast and easy such as powder, granules and opaque solids. Six measurements a second means more product area is being measured and improves averaging.

Also, individual piece measurements, using built-in product detection, are available. Connection to any PC on the network provides easy operation with suitable software.

EasyMatch QC color calibration software

Powerful, versatile and easy to integrate into your existing process systems, EasyMatch QC color calibration software is the perfect complement to HunterLab instrumentation.

EasyMatch QC provides you with unlimited ability to record and analyze measurement data. For online instruments the EasyMatch OL-ST software is used with unlimited storage for standards and tolerances.
