The DS-700d Portable Spectrophotometer is a precision instrument designed for detailed colour measurement.

Dual Optical Path: The DS-700d utilises a dual optical path system. This functionality improves measurement accuracy by allowing the instrument to sample light from two different paths, yielding precise and reliable data.

Intelligent Auto Calibration: The DS-700d includes an auto calibration system that adapts the device's settings to maintain consistent accuracy across varied conditions.

400-700nm Wavelength: It operates within the visible light spectrum, spanning 400-700nm wavelengths, ensuring comprehensive colour data that aligns with human visual perception.

10nm Intervals: Readings are captured at 10nm intervals, offering detailed colour analysis and the ability to discern minor colour differences.

Integrated Camera: An incorporated camera aids in targeted measurements, streamlining the process and minimising potential errors.

Connectivity: The DS-700d offers Bluetooth connectivity for the dedicated CM App and compatibility with our specialised Windows software, catering to various data management preferences.

Touchscreen: Its 3.5" TFT touch screen interface provides a straightforward user interaction, simplifying operations.

Overall, the DS-700d Portable Spectrophotometer is engineered for users seeking precision, consistency, and a technical approach to colour measurement.

Design Samples

Dual optical path array sensor

The dual optical path design monitors the energy fluctuation of the light source whilst measuring the sample data, to reduce interference during the measurement and obtain better measurement repeatability. The usage of large-area dual-array sensors provides a higher spectral response sensitivity, and ensures fast measurement speed, accuracy, stability and consistency between multiple devices.

Intelligent auto calibration

The white calibration tile is made of Zirconium dioxide (ZrO2) which has a reflectance of more than 90% which results in a more stable calibration.
When the instrument is placed in the intelligent calibration base unit, the instrument will automatically calibrate using the built-in white calibration tile, so there is no need to manually calibrate which saves time and effort. The white tile is made using ZrO2 to ensure excellent resistance to scratch, discoloration and weathering over time.
