Portable spectrophotometer LSP-A20

Portable spectrophotometer LSP-A20


Portable spectrophotometer LSP-A20 is adopted with every test calibration ETC technology, where the standard white boards included in the optical system for reliable, accuracy of every measurement. The pulse xenon lamp is used for measurement of UV samples with wide wavelength range. Its Built-in camera helps to view measured area precisely. The automatic gloss compensation technology helps in measurement data for the surface of different gloss.
