The Use Of Portable Spectrophotometers In Color Management

Many industries need color management in order to ensure that all like products or items leave the factory with consistent coloring

. Its through the use of a spectrophotometer that everything from hamburger buns and grape juice to car finishes and clothing dyes come out looking the same, every time.

As mentioned, portable, hand held spectrophotometers give measuring technicians a high degree of flexibility and autonomy. These instruments have wireless communications capabilities and a very clear, easy to read LED screen that can be viewed in virtually any environment. As to actual function, the portable models provide the same results and technological features as the larger bench top models.

A technician in a huge food manufacturing plant, for example, can take this measuring device to whatever area of the plant he or she needs to work in, rather than bringing food samples to the measuring department or area. This makes jobs get completed faster, which saves time and money for the manufacturer.

Engineers using spectrophotometers can also easily visit other sites, perform whatever color measurement tasks are required, store the data on a hand held instrument, bring the instrument back to the main plant and then study and share the data as necessary.

The newer portable models are ergonomically designed. They fit easily into the hand and are made with a holding surface that keeps them from slipping and causing the laser to mis-read the object being studied. Several models are available, depending on the requirements of the task. A vertical model is ideal for small spaces, and its design allows for it to be accurately positioned on un-uniform surfaces.

When measurements of larger surfaces are required, the horizontal model is the best choice. It features a navigation wheel, which is somewhat like the mouse used with a computer, rather than the standard buttons.

What a lot of engineers like about the newer portable spectrophotometers is their menu displays, which make it easy for anyone to navigate screens and choices. Operators can program the instrument to quickly re-load functions that are most commonly used. For example with a few clicks, a technician can recall specific menus with customized settings and view commonly used color targets.

These devices are compatible with Bluetooth, making for easy wireless access from just about anywhere. They can also connect through a USB cable, when the need arises to download directly to a computer.

In summary, spectrophotometers are now available in small, convenient, hand held models that allow technicians to perform a variety of color measurement tasks anywhere. Expect their use to continue to grow in all industries where the accurate measurement of color is demanded.
