A spectrophotometer measures the full visible color spectrum (typically 400–700 nm). It offers significantly higher precision and enables detailed evaluations – including spectral curves, ΔE values, and color distance measurements. It is the preferred choice for demanding applications in labs or color development environments. learn more..

The core difference between a colorimeter and a spectrophotometer lies in their light measurement methods. A colorimeter measures color values based on the tristimulus method (e.g. LAB or RGB) and compares the sample to a reference. It's ideal for quick, repeatable measurements under consistent conditions – such as in production or incoming goods control.

Standard models are available in a range of sizes, starting from small desktop units which are roughly the size of 60 x 40 x 40 cm, and extending to larger units which are about 120 x 60 x 80 cm based on what you need them for.

The accuracy of colors is determined by comparing the values of the colors (L*a*b*) of a sample with a standard reference sample using tools such as spectrophotometers. The variation is measured as ΔE. The smaller the value of ΔE, the more accurate, the nearer to the target color.

Yes, we offer free samples for test, you are welcome to order samples to experience our excellent quality and service.

There are many factors that can influence accuracy such as surface roughness, temperature, substrate material, and calibration settings. For ferrous metals, external magnetic fields can also distort measurements. Proper calibration and preparation will help reduce the impact of these factors.

Our machine is packed by standard export wooden box, it won’t be damaged. We’ve delivered many testing machines abroad by sea or by air without damage.

Spectrophotometers can only measure haze if it has haze measuring capabilities, as many measure color and transmittance.

L*a*b* is an L*a*b* color space. The L* is a measure of lightness (as 0 = black, 100 = white), a* indicates the green to red axis, and b* indicates the blue to yellow axis. It is also common in color measurement in terms of precision and reliability.

To keep a neutral background, helping to reduce color distortion and bias.

To determine haze, haze meters are used in multiple industries such as plastic, glass, film, coating, and displays. This ensures that all optical quality of the product is in the appropriate specification, including aesthetic compliance and meeting the intercontinental quality standards.
