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.

1. When I received NH310/NH300 colorimeter and perform measurement, why the measured data is abnormal?
After receiving NH310/NH300, you have to perform white and black calibration manually when first starting.
2. In which condition, manual white and black calibration and auto calibration are required for NH310?
a. It’s needed to perform manual calibration for NH310 when first starting.
b. In the subsequent starting, NH310 will perform auto calibration at startup. No need to perform manual calibration.
c. Suggestion: it’s best to perform manual calibration once a week or when NH310 measured data is not accurate.
3. In which condition, manual white and black calibration for NH300 is required?
a. It’s needed to perform manual calibration for NH300 when first starting.
b. In the subsequent starting, no need to perform manual calibration.
c. Suggestion: it’s best to perform manual calibration once a week or when NH300 measured data is not accurate.
4. How to replace NH310 measuring aperture?
There are three measuring apertures for NH310: Φ8mm (standard accessory), Φ4mm (standard accessory), extended Φ8mm (optional accessory)
a. Turning on
b. Removing measuring aperture, install the needed measuring aperture.
c. Select “Settings-Aperture Setting” in main menu to select corresponding measuring aperture.
d. After selecting aperture, the instrument will display “White and Black Calibration” interface. White and black calibration must be performed.
