CHN SPEC DS-37D Benchtop Spectrophotometer (d/8, 360nm-780nm, XLAV ΔE*ab 0.12)

The CHNSpec DS-37D Benchtop Spectrophotometer is a high-precision color analysis device, providing a comprehensive solution for quality control (QC) and Color Matching processes. Positioned in the high-end product range, the DS-37D delivers powerful measurement performance with extremely tightly controlled inter-instrument agreement, creating an optimal balance between laboratory-grade accuracy and investment cost.

Outstanding Features

Dual Optical Path Design: Similar to the brand’s most premium models, the DS-37D utilizes a dual optical path system that simultaneously collects sample data and reference sensor data. This eliminates light source fluctuations, maintaining outstanding long-term stability.

Impressive Inter-Instrument Agreement: With an inter-instrument agreement of ΔE*ab ≤ 0.12, the device ensures the consistency of color data when exchanged between different laboratories, factories, or supply chains.

Accurate Fluorescent Sample Measurement: The device is equipped with a continuous UV control and adjustment system, enabling the most accurate and reliable measurement of materials containing optical brightening agents (OBA) or fluorescent colors.

Support for Diverse Sample Physical States: The DS-37D features a spacious transmission measurement chamber, combined with specialized accessories to easily measure various types of samples such as: solids, powders, granules, pastes, or liquids.

Automatic Temperature and Humidity Compensation: A built-in smart algorithm automatically analyzes and compensates for the effects of ambient environmental conditions (temperature, humidity), ensuring the final measurement data is unaffected by external factors.
