3nh PS230 Spectrophotometer and Color Meter

3nh PS230 Spectrophotometer and Color Meter

In the context of industrial competition, controlling and maintaining product color consistency batch-to-batch is a vital factor in retaining customers. However, large laboratory spectrophotometers are often highly expensive and cannot be deployed in the field. The 3nh PS230 spectrophotometer stands as a breakthrough solution – a compact, pocket-sized portable color measurement instrument that delivers the high precision of grid spectrophotometry technology at an exceptionally optimized cost for enterprises.

Overview of the 3nh PS230 Spectrophotometer

The 3nh PS230 is a next-generation spectrophotometer optimized for high mobility. The device utilizes an international standard d/8 optical geometry (diffuse illumination, 8-degree viewing angle) – the benchmark architecture recommended by the International Commission on Illumination (CIE) for material color evaluation.

By integrating advanced diffraction grating light-splitting technology alongside a CMOS matrix spectral sensor, the PS230 precisely quantifies the spectral reflectance of individual light wavelengths, yielding color measurement accuracy that far surpasses conventional colorimeters on the market.

Key Features of the 3nh PS230

💡 Accurate Diffraction Grating Spectrophotometry Technology

Unlike low-cost instruments that only measure color based on basic color filters, the 3nh PS230 utilizes an optical diffraction grating system. This technology enables the device to conduct an in-depth analysis of the spectral range from 400nm to 700nm, helping to detect the smallest color deviations and completely preventing metamerism (a phenomenon where colors appear identical under one light source but differ under another).

💡 Ultra-Portable and Fashionable Pocket-Sized Design

The PS230 features a minimalist, ergonomic form factor that is extremely compact and ultra-lightweight. Technicians can effortlessly carry the device in a pocket to conduct on-site field inspections across manufacturing floors, warehouses, or job sites comfortably without any hassle.

💡 Dual Integrated SCI and SCE Measuring Modes

• SCI (Specular Component Included): Measures the core color of the material, eliminating variables caused by surface gloss or roughness.
• SCE (Specular Component Excluded): Accurately quantifies real-world color in strict accordance with human visual perception.
  This premium feature enables the PS230 to successfully handle everything from ultra-glossy and matte surfaces to rough textures.

💡 Diverse Color Spaces and Rapid Pass/Fail Evaluation

With just a single click taking less than 1.5 seconds, the sharp color screen of the PS230 instantly displays:

• Standard Color Spaces: CIE Lab, XYZ, Yxy, LCh, RGB…
• Advanced Color Difference Formulas: Delta Eab, Delta E00, Delta E*cmc…
• Intelligent Warning Mode: Automatically calculates and displays a “Pass” or “Fail” alert based on pre-set Delta E tolerances, allowing operators to screen out defective items rapidly on production lines.

💡 Smart Mobile App and PC Software Connectivity

The 3nh PS230 supports wireless Bluetooth technology and a convenient USB-C port:

• Connect to smartphone applications to synchronize data to the cloud, sharing measurement results instantly with partners or supervisors.
• Connect to specialized PC color management software to store international color card libraries (Pantone, RAL), track color variation trends, and export professional QC reports.
