Product Description

Product Description

Desktop Spectral Transmittance/Reflectance/Color Difference Tester
1.Product Introduction
The GA-7 Desktop Spectral Transmittance/Reflectance/Color Difference Tester is an instrument usd for testing transmittance, reflectance, color values, and color differences. This instrument complies with the technical requirements of GB2680-1994 and GB/T3979 standards. The equipment comes standard with a control computer and supporting software.

Equipment introduction
This instrument can measure the transmittance and color values of all transparent or semi-transparent flat objects, as well as the reflectance and color values of all transparent or opaque flat objects, and calculate color differences.

System features

1. Resistance to ambient light interference
2. Capable of continuous long-term operation
3. Computer-controlled operation with excellent scalability
4. High stability of core system components (e.g., spectrometer and optical fibers are all original imported parts)

Equipment functions 

1. Capable of outputting spectral transmittance and reflectance in the 380-1100 nm range and displaying spectral curves.
2. The computer stores the spectral distributions of D65 and A light sources, and can automatically calculate visible light integral transmittance, visible light integral reflectance, and color values under D65 and A light source environments, with real-time display on the screen.
3. Can export spectral transmittance and reflectance curves.
4. Can test diffuse reflection and specular reflection of samples.
5. Can measure XYZ values, Lab* values, etc., of samples and calculate color differences between different samples.
6. The default spectral wavelength interval is 5 nm, and the interval can be adjusted in multiple gears based on a 5 nm base.
7. All data are saved in independent files and can be exported to Excel files.
8. All test operations are performed via the control computer. Test results can be saved, queried, and printed (printer not included in the standard configuration).

 

Usage environment
1. Ambient temperature: 0ºC to 40ºC
2. Environmental humidity: <70%
3. Power supply mode: AC220V5A
4. Avoid vibration
