3nh TS7700 Handheld Spectrophotometer (400~700nm; 10nm)

3nh TS7700 Handheld Spectrophotometer (400~700nm; 10nm)

In the modern industrial manufacturing era, maintaining absolute color consistency between incoming and outgoing batches is the key to preserving a business’s reputation. Older-generation conventional colorimeters or early-stage spectral scanners are often prone to data drift when workshop temperatures fluctuate, and they remain completely helpless against metamerism or materials containing optical brightening agents. The 3nh TS7700 Handheld Spectrophotometer is a comprehensive upgrade solution – a premium handheld instrument featuring an ultra-fine 10nm spectral interval and a dedicated UV light source, helping enterprises standardize their QC processes in the most scientific, objective, and professional manner.

Overview of the 3nh TS7700 Spectrophotometer

The 3nh TS7700 is a new-generation dedicated handheld spectrophotometer, perfectly optimized by the 3nh brand for mobile inspection capabilities across workshops, warehouses, and laboratories requiring exceptional accuracy and processing speeds. The device utilizes the international standard d/8 optical geometric structure (diffuse illumination, 8-degree viewing angle), fully and strictly meeting the stringent regulations of the International Commission on Illumination (CIE No.15), ISO 7724/1, ASTM E1164, and DIN 5033.

The core strength that establishes the TS7700’s leading position in the mobile segment lies in its diffraction grating spectral separation technology combined with a high-resolution dual-array CMOS matrix spectral sensor system. The instrument dissects the spectral energy of reflected light from a wavelength range of 400 nm to 700 nm with an extremely small 10nm interval step, allowing for the lightning-fast detection of the smallest micro-chromatic deviations on material surfaces.

Outstanding Features of the 3nh TS7700

💡 Ultra-Fine Spectral Analysis Capability (400~700nm; 10nm Interval)

Featuring a continuous spectral scanning range that completely covers the visible light spectrum with an extremely small 10nm bandwidth interval, the 3nh TS7700 can reconstruct the material’s spectral curve in detail. This technology enables the device to completely eliminate errors caused by metamerism, ensuring that measurement results attain maximum objectivity and maintain excellent repeatability across tens of thousands of continuous triggers in industrial environments.

💡 Integrated Independent UV Light Source – Standard Measurement for Fluorescent Materials

A highly valuable upgrade of the TS7700 compared to lower-tier models is the integration of a dedicated UV light source. This feature allows the device to activate and accurately analyze optical brighteners and fluorescent whitening agents commonly found in high-end printing paper, textiles, plastic films, or traffic reflective films, ensuring that white color data does not drift under any inspection light source.

💡 Smart and Flexible Switchable Multi-Aperture System

The TS7700 offers maximum flexibility for enterprises by supporting interchangeable configurations for multiple measuring apertures (such as Phi 8mm, Phi 4mm, or Phi 1x3mm) depending on the geometric characteristics and dimensions of the product. Technicians can use a large aperture for standard flat surfaces or quickly swap to a small aperture to measure angular details, miniature components, and complex curved surfaces without having to invest in multiple separate instruments.

💡 Simultaneous Integration of Dual Advanced Measuring Modes: SCI and SCE

The advanced optical system of the TS7700 allows technicians to deeply analyze material characteristics through two flexible measurement modes:

• SCI (Specular Component Included): Measures the actual inherent core color of the material, eliminating all interference from matte surface gloss or the roughness of paint films and plastic pellets.
• SCE (Specular Component Excluded): Measures the actual color shade displayed to the consumer’s eye, perfectly serving the visual appearance evaluation of the product according to real-world visual perception.

💡 Intuitive Target Area Positioning via Real-Time Camera

To completely eliminate errors caused by misaligning the measuring head (especially when measuring tiny details with the Phi 4mm aperture), the 3nh TS7700 integrates a real-time Camera positioning system that visually displays a sharp target area directly on the touch screen. This helps technicians place the measuring head perfectly flush against the exact center of the test point, eliminating external stray light leakage.

💡 In-Depth Data Management PC Software Connection and Ultra-Large Memory

With a significantly upgraded memory capacity, the TS7700 allows for the storage of large volumes of standard sample data and actual measurement results. Via a high-speed USB data transmission port or smart Bluetooth, the device synchronizes perfectly with intensive color management software on computers, supporting chromatic variation trend charts, managing digital color card libraries (Pantone, RAL), and automatically exporting professional PDF/Excel Quality Control Reports (QC Report) to send to major partners.
