The evolution of the benchtop spectrophotometer is no longer just about improving ΔE values. The next frontier is intelligence—using technology to eliminate human error, streamline complex workflows, and extract more meaningful data from every measurement. The 3NH TS8500S Benchtop Spectrophotometer is a flagship instrument designed precisely for this era, positioning itself not just as a measurement tool, but as an automated color control workstation.
But does its “intelligent” feature set translate to tangible benefits in a busy laboratory? This review takes a deep dive into the TS8500S’s sophisticated automation, robust performance, and overall value proposition for modern, high-throughput quality control.
First Impressions: A Glimpse into a Smarter Workflow
The TS8500S immediately stands out with its professional and robust design. The instrument feels substantial and stable, a necessity for mitigating environmental vibrations that can impact high-precision readings. The large, responsive touchscreen interface is modern and intuitive, providing clear access to a wealth of functions.
However, the true differentiator is revealed inside the sample compartment. The presence of a high-resolution integrated camera and the mechanism for an automated, motorized measurement head signal that this is an instrument designed for a new level of operational ease and repeatability.
Key Features: Deconstructing the “Intelligent” Design
The TS8500S is built around a core philosophy of automation and data integrity. Its features are designed to work in concert to achieve this.
- Dual-Camera Positioning System: This is a standout feature. The TS8500S combines a preview camera for gross positioning with a high-resolution micro-camera for fine positioning. On the touchscreen, you see a live video feed of your sample. This allows you to precisely target the exact spot you want to measure, which is invaluable for patterned textiles, mottled plastics, or small parts. It eliminates the guesswork and ensures measurement consistency across operators.
- Fully Automated Measurement Cycle: The motorized measurement head does more than just lower itself. It provides perfectly consistent, programmable pressure for every reading, completely removing a major source of human error and variability. This automation is crucial for achieving the instrument’s exceptional stated repeatability and for high-volume testing where operator fatigue can become a factor.
- High-Precision Optical Engine: At its heart, the TS8500S utilizes a high-performance grating monochromator system. This provides superior spectral resolution and low stray light compared to filter-based systems, resulting in more accurate measurements of deep shades and complex effect pigments. With an inter-instrument agreement of ≤ 0.08 ΔE*ab and a remarkable short-term repeatability of ≤ 0.015 ΔE*ab, it delivers true laboratory-grade performance.
- Programmable UV Control: For industries dealing with papers, textiles, or plastics containing optical brightening agents (OBAs), precise UV control is essential. The TS8500S allows for accurate calibration of the UV component to match standard D65 daylight conditions, ensuring that measurements are consistent and comparable, regardless of the instrument’s location.
The Software Experience: From Data to Insight
The hardware’s potential is fully unlocked by 3NH’s comprehensive ColorMaster software suite.
- Visual Sample Management: The integration of the camera system with the software is seamless. You can save images alongside spectral data, creating a rich, visual record of every sample measured. This is powerful for audit trails, reporting, and resolving disputes with visual evidence.
- Advanced Formulation and QC Modules: The software is capable of handling complex tasks like color matching (formulation) and strength assessment. For quality control, it allows for the setup of sophisticated pass/fail tolerances using all standard color difference equations (ΔEab, ΔEcmc, ΔE*00). The ability to generate detailed statistical reports and trend charts helps labs move from reactive checking to proactive process control.
- User Management and Data Security: Features like multi-level user passwords and permission settings ensure that calibration and standard data are protected from unauthorized changes, which is critical for maintaining data integrity in multi-user laboratory environments.
Real-World Performance: The TS8500S in Action
We evaluated the TS8500S in several demanding scenarios to test its mettle.
- Automotive Interior Trim Matching: Matching a plastic dashboard component to a fabric seat material is challenging. The TS8500S’s camera system allowed the operator to precisely avoid the stitching on the fabric and target the exact nap direction, ensuring a representative measurement. The high repeatability ensured that multiple readings across both materials were reliable, leading to a perfect visual match.
- High-Volume Paint Batch Release: In a paint manufacturing QC lab, the automated head was a game-changer. Dozens of batch samples could be measured per hour with zero variation in measurement pressure. This dramatically increased throughput and data consistency, and the excellent inter-instrument agreement meant that batches approved at the plant were also approved by customers using the same model instrument.
- Small Plastic Part Inspection: For measuring small, critical areas on injection-molded parts, the zoom function of the positioning camera was invaluable. It allowed operators to see exactly where the 8mm aperture (or optional smaller apertures) would land, preventing erroneous data from measuring a edge or a curved surface improperly.
Ideal Applications and Users
The 3NH TS8500S is ideally suited for labs where precision, throughput, and data integrity are non-negotiable:
- Corporate Color Standards Laboratories: For establishing and communicating definitive global color standards.
- R&D and Formulation Labs: Where developing new colors and materials requires the highest data accuracy.
- Industries with Complex Materials: Automotive, textiles, plastics, and coatings where samples are often non-uniform.
- High-Throughput QC Labs: Facilities that need to process a large number of samples daily without compromising on data quality.
Pros and Cons: A Balanced Verdict

Final Verdict
The 3NH TS8500S Benchtop Spectrophotometer is a significant leap forward in intelligent color measurement. It successfully addresses some of the most persistent challenges in the QC lab: operator variability and the difficulty of measuring complex samples. By combining a high-precision optical engine with groundbreaking automation and visual positioning, it doesn’t just measure color—it captures context.
For laboratories ready to invest in a solution that enhances both the accuracy and efficiency of their color control processes, the TS8500S is an outstanding choice. It is a powerful, forward-thinking instrument that justifies its position as a flagship model, capable of handling the most demanding applications today and well into the future.
