Portable Spectrophotometer NPS-201 has a wavelength range of 360 to 780nm for precise measurement. It offers four measuring apertures of Φ11mm, Φ10mm, Φ6mm, and Φ3mm. This unit is powered by a full-band balanced LED light source combined with a xenon lamp for reliability. It utilizes a grating-based spectroscopic method to ensure accurate color analysis. Our spectrophotometer includes an intelligent automatic calibration system for consistent long-term performance.
