Portable spectrophotometer SP-A20

The Portable Spectrophotometer SP-A20 incorporates Enhanced Test Calibration (ETC) technology, featuring standard whiteboards in its optical system to ensure reliable and accurate measurements. It utilizes a pulse xenon lamp for measuring UV samples across a wide wavelength range. Additionally, its built-in camera facilitates precise viewing of the measured area. The spectrophotometer is equipped with automatic gloss compensation technology, enhancing the accuracy of measurement data for surfaces with varying gloss levels.
