Spectral colorimeter AMT517 series are economical models to measure the color difference. Instrument is with auto calibration to make it simple in operation. It contains 30 kinds of parameters and 26 kinds of illuminants. AMT519 is with switchable apertures to measure samples with different sizes.

1. Different apertures

2. Auto calibration

3. SCI/SCE: It supports both SCI and SCE test which is more consistent with result of visual method.

4. Many different kinds of test parameters, Opacity, whiteness index, yellowness index and other 30 kinds of test parameters

5. Provide 26 Kinds of Illuminants for Choice

6. Good repeatability for stable measurement (Delta E*ab 0.08)
