The 3nh PS02 is a flagship portable Skin ColorReader engineered for mobile detection, high-end aesthetic medical services, and skincare efficacy research. Utilizing an international standard 45/0° circumferential uniform optical system paired with nanometer integrated spectroscopic components, it achieves superior repeatability (ΔE*ab ≤ 0.03) and national metrology certification in a lipstick-sized 88g frame. The PS02 excels in turning national metrology-approved color measurement precision into an accessible, pocket-sized device. Delivering high-precision, traceable metrics—Individual Typology Angle (ITA°), Melanin Index (MI), Erythema Index (EI), and CIE LAB—in a 1-second single touch, PS02 bridges mobile convenience with rigorous scientific proof.

1. 1-Second Fast Measurement & 4 Core Metrics Output

A single 1-second skin contact measurement outputs four vital skin parameters simultaneously:


  • Individual Typology Angle (ITA°): Higher values indicate lighter skin tones; simplifies precise skin typology categorization.

  • Melanin Index (MI): Quantifies skin pigmentation level to track whitening treatments and spot reduction.

  • Erythema Index (EI): Measures redness and inflammation intensity for sensitive skin and soothing care evaluation.

  • CIE LAB Color Space: International standard color coordinates for precise objective color mapping.


4 Core Metrics Output


2. High Precision, Metrology Certification & Traceable Data

  • Illumination/Viewing Geometry: 45/0°, compliant with international and national standards including CIE No. 15, GB/T 3978, and ISO 7724-1.

  • Repeatability: ΔE*ab ≤ 0.03 (after preheat and calibration, based on the average of 30 measurements of the white tile at 5-second intervals).

  • Wavelength Range: Full coverage from 400 to 700 nm.

  • National Metrology Certification:Certified by national metrology authorities.

    Advanced Spectral Technology: Featuring a nano-integrated spectral device combined with a silicon photodiode array (dual-row, 16-channel configuration), the instrument accurately captures true skin color data and detects even subtle changes in skin tone after the use of brightening products. Replacing subjective visual assessment with precise instrumental measurement, it provides more convincing data for efficacy evaluation and supports product claims with objective measurement results.

FAQs About PS02 ColorReader

The color may be quantified in L*a*b* (CIELAB units), RGB values, CMYK (printing), and ΔE (color difference). Colorimetric assessment measures also apply spectral reflectance and absorbance (A), particularly in liquids and solutions.

The color measurement test applies a colorimeter or spectrophotometer to evaluate the way a sample reflects or absorbs light. It is given in objective color values (L*a*b*, RGB, or absorbance) and is usually contrasted to a standard in quality control or compliance.

The color measurement theory is the quantification of the interaction of materials with light, either absorption, transmission, or reflection. It employs standard colour spaces (such as CIELAB) and devices (colorimeters, spectrophotometers) to code the visual colour into objective and reproducible data.

Color is a qualitative and quantitative measure. Qualitatively, it can be characterized by the hue, the saturation, and the brightness. It is quantified in terms of color spaces, such as L*a*b* or RGB, in terms of numerical values based on devices such as colorimeters or spectrophotometers.

Color measurement methods involve visual approximation (against color charts), colorimetry (by means of filters and detectors), spectrophotometry (a more detailed spectral analysis), and image analysis by computer. These are color measurement methods that are applied in the laboratory, production, and quality assessment.
