Intended Use：
Featuring high stability and precise measurement of density and colorimetric data, this instrument holds a leading position in the field of portable spectrodensitometers. Equipped with various measurement apertures, it is widely utilized in ink printing, papermaking, traffic signage, textile dyeing, research institutes, quality inspection agencies, and laboratory environments.
Operating Principle：
Positioning is achieved via a light spot at the measurement aperture. To align: enter the standard or sample measurement interface, then press and hold the "Measure" button to project the light spot. Adjust the device position by matching the spot with the target area of the sample to ensure precise targeting.
Product Features：
- Illumination Positioning: Features proprietary light-spot positioning technology for fast and convenient alignment, emphasizing an ergonomic and user-centric design.
- Auto-Calibration: No manual black/white calibration is required upon startup, significantly enhancing efficiency and convenience for high-precision color difference measurements.
- High Stability: Standard deviation is ΔE*ab＜0.08 (Average of 30 measurements on a standard white plate).
- Standard Illuminant: Utilizes the internationally recognized D65 standard illuminant.
- Multiple Color Spaces: Supports various color spaces, allowing users to select the display mode that best suits their specific needs.
