Benchtop Spectrophotometer

Application:

The Benchtop Spectrophotometer is a powerful and highly precise instrument designed for 

demanding color applications. Its ability to measure Specular Component Included (SCI) and 

Specular Component Excluded (SCE) simultaneously, coupled with superior inter-instrument

 agreement, makes it an ideal tool for advanced colour formulation and quality control, as well as 

solving complex colour challenges. It is primarily used in industrial sectors with stringent colour 

management requirements, such as coatings, plastics, textiles, automotive and cosmetics.

Advantage:

1. Transmission D/0 structure and reflection D/8 structure

2. Dual Optical Paths Spectrum Analysis Technology This technology can simultaneous access to both 

measurement and instrument internal environmental reference data to ensure instrument accuracy and long-term stability.

3. Compatible with SCI/SCE measurement, and supports SCI+SCE simultaneous fast measurement The D/8 l

ighting observation condition recommended by the International Commission on Illumination is adopted to meet 

the measurement needs of various industries; it can perform specular reflection (SCI) and specular reflection 

excluding (SCE) measurements to gain a fuller insight into color data changes. It also supports simultaneous 

and rapid measurement of SCI+SCE, with a test time of less than 4 seconds.

4. Equipped with Android operating system and rotatable capacitive touch screen The instrument APP 

based on the Android operating system and the 7-inch large touch screen are as smooth and convenient 

as daily mobile phone operations, making them easier to use. 

5. Open transmission sample compartment, accommodating large-size samples 

The open transmission sample compartment is not limited by sample size and can easily handle even large-sized films.

6. Rich accessories 15 standard accessories and 12 optional accessories to meet the testing 

needs in different scenarios.

       

7. The instrument comes with an accessories drawer for easy protection and storage of accessories.

8. Reflection measurement aperture can be switched Four measuring apertures, the instrument 

automatically identifies the aperture and adjusts the optical path, no need to do it manually.

9. Four UV measurement modes to make fluorescence visible.
