Portable Spectrophotometer NPS-103 uses a 45°/0° ring illumination optical structure for enhanced precision. It offers two measurement aperture options for flexibility with different sample sizes. Our unit employs grating spectroscopic technology to accurately disperse light into wavelengths. It has an intelligent automatic calibration for precise results without manual intervention. This spectrophotometer includes a 3.5-inch full-color display for clear visibility and easy navigation.
