FAQs About Spectrodensitometer
Look for dirty or fingerprinted glass along the optical path, recalibrate with standards, and check the set-up for outside light so that it is controlled. If the problems still exist, please reach out to the helpdesk or book a service with your professional service.
High Measurement Accuracy and Stability: Low ΔE fluctuation (e.g., NH300: ΔE < 0.07; NR10QC: ΔE ≤ 0.03 short-term repeatability); Reliable sensors (CMOS dual-beam/silicon photodiode) and long-lasting light sources (1.6M–3M measurements over 5 years).
User-friendly Design and Convenient Operation: Intuitive interfaces (e.g., NH300’s “fool-proof” operation), auto-calibration, and ergonomic grips for extended use; Versatile positioning (light/cross alignment) for precise measurements.
Robust Design: Our colorimter instruments are designed to withstand rigorous use, providing long-term reliability. Rechargeable lithium batteries enable 5,000–6,000 measurements per charge (e.g., NH300/TS7030), ensuring cost-effective durability.
PC Software Support for Functionality Expansion: PC software (e.g., CQCS3) supports color difference analysis, chromaticity indexing, and sample library management.
Global customer support: Our global presence across regions ensures you get the service and maintenance support you need to keep your instrument at peak performance.
Multiple Measurement Apertures and Application Scenarios: Multiple measurement apertures, different models have different measurement apertures and some models offer multiple optional apertures. Applicable to plastic electronics, paint and ink, textile and garment printing and dyeing, printing, ceramics, automotive, food, medicine and other industries for color quality control and color difference detection.
A spectrophotometer illuminates a sample with light or passes light through it and records the reflected or transmitted light over the wavelength range. It transforms this data into color coordinates (such as L*a*b*), allowing accurate color assessment as well as color comparison to standards.
Common sources like D65, TL84, and CWF mimic daylight, store, home, and fluorescent lighting, and are used to provide conditions for dependable color comparison.
A spectrophotometer measures the full visible color spectrum (typically 400–700 nm). It offers significantly higher precision and enables detailed evaluations – including spectral curves, ΔE values, and color distance measurements. It is the preferred choice for demanding applications in labs or color development environments. learn more..
The core difference between a colorimeter and a spectrophotometer lies in their light measurement methods. A colorimeter measures color values based on the tristimulus method (e.g. LAB or RGB) and compares the sample to a reference. It's ideal for quick, repeatable measurements under consistent conditions – such as in production or incoming goods control.
D/8° and 45°/0° are two different illumination methods with distinct optical geometries. The D/8° illumination is suitable for general industries, and delivers better performance in color difference comparison and color measurement especially for high-gloss products. For the packaging and printing industry, the 45°/0° illumination is recommended.
Plastic, paint, ink, ceramic, textile, coating
Samples with metallic luster, pearlescent, glitter, or texture
Situations requiring consistent data with laboratory spectrophotometers
Applications needing SCI (including specular reflection) / SCE (excluding specular reflection) switching
Printing, packaging, paper, ink, matte non-metallic materials
Products focusing on human eye direct visual matching
Standard color matching in printing & packaging industry
With metallic/pearlescent/glitter effect → choose D/8°
Printing, paper, packaging, matte products → choose 45°/0°
Want universal use for multiple materials → choose D/8°
