3nh TS7708 Spectrophotometer (3 apertures; double 40 array sensor)

3nh TS7708 Spectrophotometer (3 apertures; double 40 array sensor)

In industries with stringent color standards such as automotive parts, electronics, premium textile dyeing, industrial coatings, and plastics, owning a portable color measurement device that delivers laboratory-grade accuracy is vital. The 3nh TS7708 spectrophotometer is the perfect answer – a flagship handheld device that brings a breakthrough with its double 40-element array sensor system and the flexibility of 3 switchable measuring apertures for all types of product surfaces.

Overview of 3nh TS7708 Spectrophotometer

The 3nh TS7708 is the most premium portable spectrophotometer in the TS series by 3nh. The device utilizes the international standard d/8 optical geometry (diffuse illumination, 8-degree viewing angle), perfectly complying with the strict regulations of the International Commission on Illumination (CIE), ISO, and ASTM.

The core power that makes the 3nh TS7708 lead the portable segment lies in its grating spectrophotometry technology combined with a Double 40 Array Sensor system. The device smoothly separates visible light energy across the 400nm to 700nm wavelength range, delivering measurement results with outstanding repeatability and supreme reliability.

Advanced Features of 3nh TS7708

💡 State-of-the-Art Double 40 Array Sensor Technology

Completely distinct from conventional colorimeters that are prone to data drift, the 3nh TS7708 features a dual-row CMOS matrix sensor system with 40 independent filtering elements. This technology enables the device to capture color data in parallel at ultra-high speeds, automatically compensate for temperature variations, and completely eliminate interference from external stray light. Consequently, the device achieves an extremely low standard deviation for Delta E*ab repeatability (below 0.015), providing absolute stability over tens of thousands of measurements.

💡 3 Switchable Apertures – Handling Every Sample Type

Businesses no longer need to invest in multiple devices for different component sizes. The TS7708 comes equipped with 3 easily interchangeable measuring apertures, featuring smart automatic recognition on the device body:

• Large Aperture (Ø8mm): Optimized for flat surfaces and large areas such as plastic sheets, leather pieces, fabric rolls, and wall paint.
• Small Aperture (Ø4mm): Specially designed for small parts, curved surfaces, and electronic components.
• Ultra-Small Aperture (1x3mm): The perfect solution for thread samples, stitching, ribbons, or extremely narrow edges.

💡 Real-Time Camera Dual Positioning Technology

To ensure that technicians place the measuring head precisely at the center of small and complex details, the 3nh TS7708 integrates a real-time positioning camera combined with a clear illuminating indicator line. This feature completely eliminates errors caused by manual misalignment, ensuring the utmost objectivity of quality control data.

💡 Simultaneous Integration of Two Premium Measurement Modes: SCI and SCE

• SCI (Specular Component Included): Measures the core intrinsic color of the material, eliminating the effects of surface gloss.
• SCE (Specular Component Excluded): Measures the actual color shades as displayed to the human eye, serving well for visual appearance evaluation of products.

💡 Comprehensive Color Spaces and Ultra-Fast Pass/Fail Analysis

With just a single operation taking less than 1.5 seconds, the sharp graphical LCD screen of the TS7708 instantly displays the results:

• All international color spaces: CIE Lab, XYZ, Yxy, LCh, RGB…
• The most advanced color difference formulas: Delta Eab, Delta E00, Delta Ecmc, Delta E94.
• Smart warning mode: Automatically compares the measured sample with the standard sample and displays a clear Pass or Fail status, helping operators quickly screen out defective parts directly on the production line.

💡 Unlimited Connectivity and Automated Report Generation

The 3nh TS7708 features Bluetooth technology and a high-speed USB-C port. The device easily synchronizes data with advanced color management software on computers or mobile apps to manage international color card libraries (Pantone, RAL), track chromaticity trend charts of batches, and automatically export professional Quality Control Reports (QC Reports) in PDF format to send to partners.
