Ultra-high repeatability accuracy：dE*ab≤0.03

Repeatability accuracy is an important index to describe the accuracy of a spectrophotometer.

The excellent photoelectric test system ensures that the repeatability accuracy of DS-400 series spectrophotometer reaches a level that is difficult to compare with similar products.

The repeatability evaluation of the DS-400 series spectrophotometer adopts strict standards, showing excellent repeatability accuracy performance.

The calibration base and the zirconium reference of MoHS hardness 9 calibrate the instrument to ensure the long-term stability of the instrument

Compared with existing products, DS-400 series spectrophotometer does not need frequent manual calibration when in use, as long as it is placed on the calibration base, the instrument will automatically calibrate the overall instrument function and accuracy according to its own state and environmental factors, to ensure that the instrument is always in a stable state and ready to be ready.

The white board in the calibration base is the benchmark for instrument accuracy. Through long-term investment and research, the color spectrum integrates the zirconium material known as "artificial diamond" as a calibration whiteboard, and the surface Mohs hardness reaches 9. Due to the hardness and stability of the material itself, it is guaranteed that the surface of the calibrated whiteboard will not be scratched and will not change color with temperature and humidity changes. Compared with foreign and domestic similar products, ordinary industrial ceramics and even plastics are used as calibration whiteboards, which further improves the stability and durability to ensure the performance of the instrument.

The DS-400 series is available in 10 measuring calibers

In order to facilitate users to measure samples of different sizes, DS-400 series spectrophotometer supports 10 calibers for customers to use, stable type: Φ11mm, Φ10mm, Φ6mm, Φ5mm, Φ3mm, clever type: - 11mm, - 10mm, - 6mm, - 5mm, - 3mm, can be flexibly applied to a variety of different use and test conditions.

Built-in HD camera for clear observation of the area under test

The DS-400 series spectrophotometer can obtain the image of the measured area through the camera during the measurement, and can clearly locate the measured area of the sample to avoid the uncertainty caused by regional errors.

Support wechat mini program, Android, Apple, Hongmeng mobile APP

The DS-400 series spectrophotometer can be connected to a variety of mobile phones through a variety of mobile applications.

Users no longer need to transfer the color value of the sample and the real object, and can easily transfer the color data through wechat.

Users can look for the most similar colors in multiple sets of color cards.

Users can create a personal color database, input printing, coating, textile and other color card information, the created color library can be uploaded to the cloud, multi-device data sharing, color processing more convenient.

Enterprise users can create and manage their own color card information base and color recipe in the cloud, and share the information base and color recipe with their own users through a unique invitation code.

Use the powerful PC-side color management system ColorExpert

DS-400 Series spectrophotometer comes with the Windows color management system ColorExpert, which is connected to the DS-400 series spectrophotometer via Bluetooth or USB cable. ColorExpert is a full-featured color management software with four functional modules: My Colors, Color detection, color matching system, and Personal Center.
