Linshang Portable Colorimeter Selection and FAQ
Colorimeter (also named color difference meter) is widely used in paint, coatings, ink printing, packaging materials, leather fabrics, textiles, plastics and other industries. This article shows you how to choose a target colorimeter from the aspects of parameters, prices, application, principles and frequently asked questions. Linshang colorimeters contains 6 different models, which are divided into pocket colorimeters and handheld colorimeters. Among them, LS170/LS171 are pocket colorimeters, LS172/LS173/LS175 are handheld colorimeters, LS176 is spectrophotometers.
Colorimeter Features and Application
LS170 and LS171 are pocket colorimeters, they are very small in size and easy to carry. LS170 adopts 45°/0° illumination geometry, and LS171 adopts D/8°Illumination geometry. Both of them need to be operated with mobile APP and can’t be used alone.
Smart Large-aperture Colorimeter
LS175 smart large-aperture colorimeter designed with a 20mm large measuring aperture, which is special for color measurement and comparison of textured or rough surface materials.

Frequently Asked Questions
1. How accurate are Linshang colorimeters?
The repeatability is an important parameter for the accuracy of the colorimeter. Linshang colorimeter standard deviation ΔE*ab is within 0.03 (Measurement condition: the average value of 30 measurements on the white board at an interval of 3s after calibration). This repeatability is very excellent among colorimeters at the same price. Each colorimeter can pass the qualified inspection before leaving the factory to ensure it conforms to the standard of China Metrology Institute.
2. Does the colorimeter provide a formula for color matching?
Linshang colorimeters provide a color deviation prompt function according to the Lab value, which can provide a reference for color matching. It can only indicate blacker, whiter, redder, greener, yellower or bluer, but it cannot provide accurate color formulas. Only with the help of a spectrophotometer and professional color matching software can fully realized automated color matching.
3. D/8°and 45°/0°, which one is recommended?
D/8°and 45°/0°are two kinds of illumination geometry with different optical geometry design. D/8°illumination geometry is more widely used for the color comparison and measurement of high-gloss materials; 45°/0°illumination geometry is mainly used in printing and packaging industries.
4. Can the colorimeter measure light-transmitting materials (such as colored glass and film)?
Since part of the light will pass through the light-transmitting materials, the colorimeter is not suitable for color measurement of such kinds of materials; however, when place a pure color material with uniform texture under the light-transmitting material, we can measure the color difference between the standard and the sample.
5. Can the colorimeter measure powder and liquid?
Opaque liquids and powders can be put into a cuvette for color measurement.
