FAQs About Colorimeter

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.
