Take L*a*b* readings of two samples using a colorimeter or spectrophotometer and calculate color difference using the 3 formula (Delta E). The difference in 0 is the reported Delta-E, which shows how visible the change is, whereas the thresholds define the acceptability as per the application requirements.

Haze Meters are utilized in production and quality assurance in the plastics, glass, films, and coatings industries, where transparency and example are essential.

Light should be projected through the sample to measure haze, then assess the scattered light with an integrating sphere and sensors.  The haze percentage is ascertained by the scattering light to the total transmitted light.

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 light booth for color matching usually contains D65 (daylight), TL84 (store), A (incandescent) and UV light. LED may also be used in modern time for additional color matching. 

Our machine is packed by standard export wooden box, it won’t be damaged. We’ve delivered many testing machines abroad by sea or by air without damage.

Our haze meters provide consistent and accurate data as per the requirements of ASTM D1003, ISO 13468, and JIS K7105. Due to the high precision, advanced optics, and automatic calibrations, haze meters produce repeatable and precise results for glass, films, and plastics while remaining simple to operate.

This refers to assessing samples with a specific color and maintaining the same alloted time interval on all parameters to ensure neutrality of variables and reproducibility of lightness in the color. 

Common sources like D65, TL84, and CWF mimic daylight, store, home, and fluorescent lighting, and are used to provide conditions for dependable color comparison.

Ensure the source, viewing angle, and background are all neutral and standardized, and the samples are clean, and positioned for a side-by-side comparison under each light condition.
