3nh TS7030 Portable Spectrophotometric Colorimeter

Overview

The 3nh TS7030 Portable Spectrophotometric Colorimeter is an industrial-grade, handheld spectrophotometer engineered for high-precision color measurement and comparative analysis across diverse manufacturing and quality assurance environments. Operating on the CIE-standard d/8° geometry with dual-mode SCI (Specular Component Included) and SCE (Specular Component Excluded) measurement capability, the TS7030 employs a flat-field grating monochromator and a dual-row 32-element silicon photodiode array to deliver spectral data at 10 nm intervals across the visible spectrum (400–700 nm). Its optical architecture ensures compliance with ISO 7724-1, ASTM E1164, DIN 5033-7, GB/T 3978, and CIE Publication No. 15 — foundational standards for reflectance-based colorimetry. Unlike filter-based tristimulus meters, the TS7030 captures full spectral reflectance curves, enabling accurate derivation of CIE LAB, XYZ, LCh, Yxy, sRGB, βxy, and Munsell (C/2) values, as well as advanced color difference metrics including ΔE*ab, ΔE*94, ΔE*CMC (1:1 and 2:1), ΔE00, and DIN ΔE99. Designed for metrological traceability, each unit undergoes factory calibration against national standard reference materials certified by China’s National Institute of Metrology (NIM), supporting laboratory-grade repeatability and inter-instrument agreement.

Key Features

• Full-spectrum LED illumination system with spectrally uniform output across 400–700 nm — eliminates spectral gaps common in conventional white LEDs and improves signal-to-noise ratio for robust reflectance measurement.
• Dual-aperture configuration: interchangeable Φ8 mm flat port and Φ8 mm pointed port — optimized for flat surfaces, curved substrates, and confined geometries encountered in plastics, electronics, textiles, coatings, ceramics, and printing applications.
• Integrated real-time camera viewfinder with live preview — enables precise targeting of measurement areas and reduces spatial misregistration errors during manual operation.
• ETC (Every Test Calibration) technology — internal reference white tile is engaged automatically before every measurement cycle, ensuring long-term stability and minimizing drift without requiring user-initiated recalibration.
• Ergonomic, palm-fitting chassis with capacitive 3.5-inch TFT touchscreen — supports glove-compatible operation and intuitive navigation under ambient lighting conditions typical of production floors.
• Built-in rechargeable lithium-ion battery rated for up to 6,000 measurements per charge (≈8 hours continuous use) — suitable for extended field deployment and mobile QA/QC workflows.

Sample Compatibility & Compliance

The TS7030 accommodates opaque, translucent, and textured samples across solid, powdered, and liquid forms (when used with optional accessories such as powder test kits). Its Φ8 mm aperture meets industry requirements for small-area sampling in electronics assembly, automotive trim, textile dye lots, and packaging substrates. The instrument conforms to GLP-relevant operational principles: all measurements are timestamped, logged with illuminant and observer angle metadata, and support audit-ready data export. While not FDA 21 CFR Part 11-certified out-of-the-box, its SQCX software platform supports configurable user access levels, electronic signature logging, and immutable measurement history — features aligned with GMP-aligned color control processes in regulated sectors including medical device packaging and cosmetic formulation.

Software & Data Management

The TS7030 operates standalone or integrates seamlessly with 3nh’s SQCX Quality Control Software — a Windows-based application designed for statistical process control (SPC) and enterprise-level color data governance. SQCX supports multi-instrument fleet management, customizable tolerance limits per product line, automated pass/fail reporting, spectral comparison overlays, and generation of PDF/Excel-compliant test reports compliant with internal QA protocols. All raw spectral data, CIE coordinates, and derived indices (e.g., WI, YI, metamerism index Mt, colorfastness grades) are stored locally on-device (1,000 standards + 20,000 samples) and synchronizable via USB 2.0. Firmware updates and spectral library expansions are distributed through 3nh’s secure download portal — no cloud dependency or third-party telemetry.

Applications

The TS7030 serves as a primary color verification tool in R&D labs, incoming material inspection stations, inline production checkpoints, and supplier qualification audits. Typical use cases include: monitoring batch-to-batch consistency of injection-molded polymer components; validating pigment dispersion uniformity in solvent-based inks; assessing dye lot conformity in woven fabrics; verifying ceramic glaze chromaticity prior to kiln firing; and certifying color fidelity of printed brand assets against Pantone® or RAL standards. Its portability and rapid measurement cycle (~1.5 s per SCI or SCE reading) make it especially valuable for cross-site color harmonization projects where physical sample transport is impractical.

FAQ

What is the measurement repeatability specification under standard operating conditions?
ΔE*ab ≤ 0.06 (MAV/SCI mode, after thermal stabilization and white calibration; average of 30 consecutive measurements on NIST-traceable white tile at 5-second intervals).
Does the TS7030 support both 2° and 10° standard observer angles?
Yes — selectable via instrument menu or SQCX software, enabling alignment with either CIE 1931 (2°) or CIE 1964 (10°) color matching functions.
Can the device measure wet films or liquids directly?
No — direct liquid measurement requires optional accessories such as the powder test box or custom cuvette holders; for wet film evaluation, users should apply standardized drying protocols prior to measurement.
Is spectral data export available in ASCII or CSV format?
Yes — SQCX software exports full 400–700 nm reflectance spectra (10 nm steps) in plain-text CSV, compatible with MATLAB, Python (NumPy/Pandas), and third-party spectral analysis tools.
How often is recalibration required for routine use?
Daily zero and white calibration is recommended for critical applications; ETC technology maintains baseline integrity between calibrations, but formal verification against certified standards should occur at least weekly or per internal QA schedule.
