The 3nh PS01 is an entry-level, ultra-portable Skin ColorReader designed for quick skin tone reference, rapid colorimetric evaluation, and cost-effective batch deployment across chain stores and small-to-medium skincare studios. Utilizing a 45/0 circumferential uniform illumination optical system paired with nanometer integrated spectroscopic components, it packs core professional indicators into an ultra-compact body weighing just 88g. The primary advantage of the PS01 is offering quantized skin color data at an accessible price point. By sharing identical core algorithmic indicators—Individual Typology Angle (ITA°), Melanin Index (MI), and Erythema Index (EI)—with higher-end models, PS01 replaces visual estimation with objective metrics, facilitating brand-wide standardized skin analysis.
Outputs ITA° (Individual Typology Angle), skin typology classification, Melanin Index (MI), and Erythema Index (EI). Core analytical metrics align with high-end models for reliable daily skin assessment.
Requires only 1.0 second per test, minimizing client waiting time and optimizing workflow efficiency during peak store hours.
Compatible with Android, iOS, Windows, WeChat Mini-Programs, and HarmonyOS. Features automatic white-board calibration and average measurement mode (2–99 tests) to minimize accidental operator errors.
Budget-friendly pricing allows franchise brands and multi-store chains to deploy dedicated skin detection equipment across all branches, building unified service standards.
Skincare Studios & Salons: Build customer skin archives and quantify pre/post treatment results at a low operational cost.
Skincare Content Creators: Acquire multi-dimensional skin data to bolster review credibility.
Beauty Consultants & Sales: Ultra-portable design for instant skin measurements during customer consultations.
Efficacy Testing: Track subtle skin tone shifts to verify cosmetic formulation efficacy.
