As a color measurement tool used to realize color quantification and color analysis, a portable colorimeter can establish color standards, achieve color quality control. It is an indispensable precision instrument in color matching and color comparison. At present, there are many colorimeter brands on the market, with uneven quality and accuracy. Not only are there great differences in price, function and internal structure, but also in application industry. Therefore, when choosing a portable colorimeter, we must pay attention to a variety of factors to consider the portable colorimeter. In this paper, we summarized six tips for choosing handheld colorimeter.

I. Do you need portable colorimeter or spectrophotometer?

1. Portable colorimeter is a color measurement tool for psychophysical analysis, which measures human eye-brain perception. Colorimetric data are often directly read and provided as tristimulus values-X,Y,Z. The Lab and Lch values can be calculated according to the tristimulus values. By using portable colorimeter, we can know the specific color code in Pantone color chart.

2. Spectrophotometer is a color measuring instrument for physical analysis. It can analyze the reflecting transmitting properties of objects without human interpretation. Spectrophotometer can indirectly calculate colorimetric information. It is mainly used to measured light intensity ( the wavelength of light). There are many kinds of spectrophotometers, their common feature is expensive.

If you just want to achieve the color quality control in the production process, a portable colorimeter would meet your requirements. Linshang portable colorimeter can be used in many industries such as car paint spraying, test paper printing, leather fabrics, plastic metal, textile and clothing, hardware, furniture industry, plastics, rubber and other fields.   This color meter has QC testing function when providing color comparisons.

II. Color difference accuracy requirements

Color difference accuracy requirements differ in different industries. When talking about color difference accuracy, we usually mentioned ΔE*ab.  The accuracy of the handheld colorimeter can be said very high, when the ΔE*ab is within 0.08.  The ΔE*ab of Linshang portable colorimeter is 0.03. This accuracy can meet most of the color matching requirements. 

III. Portable colorimeter of "0/45" or "d/8 integrating sphere"

Common optical structures of colorimeters include "0/45 degrees" and "d / 8 degrees integrating spheres". The former can only measure smooth surfaces and cannot be used for computer color matching. The latter has stable measurement data and can measure various surfaces. It can be used for computer color matching.

IV. Simple operation of portable colorimeter

When choosing a colorimeter, the convenience of operation and portability is also required. The ease of colorimeter operation must be determined according to the user. Portable and hand-held colorimeters are user-friendly, easy to operate, capable of one-button measurement and rapid analysis.

V. Does the colorimeter have national measurement certification?

The portable colorimeter is a measurement instrument. When choosing, it is necessary to understand whether the portable colorimeter has met the national measurement requirements.

After mastering the above selection criteria, users of portable colorimeters can purchase various colorimeters on the market according to their actual needs. The Linshang portable colorimeter is independently developed by Linshang. It is a high-tech product integrating colorimetry, modern optoelectronics and computer science, which can meet the different needs of users.
