DS-807 Spectrophotometer
Model No. :
DS-807
Model No. : DS-807
Brand : CHN Spec
The DS-807 is a high-performance benchtop spectrophotometer specifically engineered with a 50mm ultra-large measurement aperture to accurately capture color data from irregular or uneven samples. By providing a broader sampling area, it effectively eliminates measurement deviations caused by local particle differences in powders, masterbatches, and textured materials.
-
Ultra-large 50mm aperture for non-uniform samples
-
Fully sealed port prevents internal dust intrusion
-
Rapid one second measurement with 10000 record storage
