3NH TS7708 Spectrometer

3NH TS7708 Portable Spectrometer

The 3NH TS7708 is a high-precision, compact spectrometer engineered for reliable color measurement and quality control across a wide range of industries. With three interchangeable measuring apertures, advanced full-spectrum LED and UV light sources, and a high-resolution sensor, the TS7708 delivers accurate and consistent color data—even on fluorescent samples. Its lightweight design and robust performance make it ideal for both lab and field use.

Features

1. Offers three different measuring apertures (Φ8mm, Φ4mm, 1×3mm) for flexibility and precision in evaluating various sample sizes and surfaces.

2. Utilizes a flat grating optical system and a silicon photodiode array sensor for stable and high-accuracy color detection.

3. Equipped with a combined full-spectrum LED and UV light source, allowing for the effective measurement of both standard and fluorescent samples.

4. Compact and portable design with a built-in camera locating system for precise sample positioning.

5. Supports both SCI and SCE specular components for comprehensive reflectance analysis.

6. Fast measuring speed (approx. 1.5s) with excellent repeatability and inter-instrument agreement for consistent results.

Applications

1. Color matching and quality control in plastics, coatings, and paint industries.

2. Fluorescent and standard sample measurement in textiles, dyeing, and garments production.

3. Color consistency verification in ceramics and electronic materials.

4. Ink and printing analysis for publishing and packaging sectors.

5. Laboratory research for colorimetric index studies, including WI, YI, opacity, gloss, and more.

6. On-site inspection and production line monitoring using the lightweight handheld design.
