New Product:Spectrophotometer With Excellent Repeatability Accuracy
DS-620
Spectrophotometer with excellent repeatability accuracy
Ultra-high repeatability accuracy: dE*ab ≤ 0.03
1. Key technology
(1) Dual optical path design improves repeatability accuracy dE*ab
≤ 0.03
The dual optical path design monitors light source energy
fluctuations while measuring the sample signal, reducing
interference during measurement, obtaining higher measurement
stability and improving the instrument's measurement repeatability
index to dE*ab ≤ 0.03. This ensures the instrument, high standards
of measurement speed, accuracy, stability and inter-stage
difference consistency. The relevant technology is protected by a
Chinese invention patent and a US invention patent.
(2) Innovative 5 micron thick nano-integrated optics
Innovation is the soul of CHNSpec. After nearly 10 years of
dedicated research, CHNSpec has adopted nano-integrated optics as
the spectroscopic device, which can achieve nano-level
spectroscopic capability with only 5 micron thickness of optics,
once again leading the direction of innovation in the industry,
crossing the technological blockade of foreign products and greatly
enhancing the technical performance of the products. The relevant
technology is protected by Chinese invention patents.

2. Product features
(1)Ultra-high repeatability accuracy: dE*ab ≤ 0.03
Repeatability accuracy is an important indicator to describe the
accuracy of spectrophotometers. The DS600 series spectrophotometers
are evaluated on the basis of a rigorous standard of repeatability,
which is unmatched by any other spectrophotometer in its class.
(2)Excellent inter-stage consistency
The superior level of technology and craftsmanship ensures that the
DS600 series has excellent inter-instrument agreement. The use of
BCRA series standard colour bricks for colour transfer and colour
value traceability guarantees an excellent level of inter-stage
variation.
(3) Calibration base and zirconium reference with a Mohs hardness
of 9 to calibrate the instrument, ensuring long-term stability
Compared to existing products, the DS600 series spectrophotometer
does not require frequent manual calibration when in use. Simply
place it on the calibration base and the instrument will
automatically calibrate the overall instrument function and
accuracy according to its own state and environmental factors,
ensuring that the instrument is always in a stable state and ready
for use.
The white plate in the calibration base is the basis of the
instrument's work. Through long-term investment and research,
CHNSpec has integrated the "artificial diamond" zirconium material
as the calibration white plate, with a Mohs hardness of 9. As the
material itself has the hardness and stability comparable to
diamond, the surface of the calibration white plate will not be
scratched and will not change colour with changes in temperature
and humidity. This is a further improvement in the stability and
durability of the calibration whiteboard compared to similar
foreign and domestic products that use common industrial ceramics
or even plastic as calibration whiteboards, ensuring the
performance of the instrument.
(4) The DS600 series supports 3 measuring apertures for selection
To facilitate the measurement of samples of different sizes, the
DS600 series spectrophotometer supports three apertures for
customer use: Φ8mm/Φ11mm+Φ4mm/Φ6mm+1*3mm, which can be flexibly
applied to a variety of different usage and testing conditions.
(5)Over 30 measurement parameters and nearly 40 evaluation light
sources available
The DS600 series spectrophotometers offer 30+ measurement
indicators such as spectral reflectance, CIE-Lab, CIE-LCh, ΔE*ab,
opacity, whiteness, yellowness, etc.; and nearly 40 evaluation
light sources to choose from such as A, B, C, D50, D55, D65, etc.,
covering almost all colour measurement indicators and light source
types in the industry.
(6) Built-in HD camera for clear observation of the measured area
The DS600 series spectrophotometer can obtain an image of the
measured area through the camera when measuring, which can clearly
locate the measured area of the sample and avoid inaccurate
measurement due to wrong area.
(7) Support WeChat applet, Android, Apple, Hongmeng mobile APP
l The DS600 series spectrophotometers can be connected to a variety
of mobile phones via a rich mobile app.
l Users no longer have to pass on the colour values of samples and
physical objects, they can easily pass on colour data via WeChat.
l Users can find the most similar colours in multiple sets of
colour cards.
l Users can create personal colour databases and enter information
on colour cards for printing, paint and textiles. The colour
libraries created can be uploaded to the cloud for easy colour
processing with data sharing across multiple devices.
l Business users can create and manage their own colour card
information library and colour recipes in the cloud, and share the
information library and colour recipes to their own users through a
unique invitation code.
WechatApp APP Mobile APP
(8) Use the powerful PC-based colour management system ColorExpert*
The DS600 series spectrophotometer is supplied with a Windows
colour management system, ColorExpert, which connects to the DS600
series spectrophotometer via Bluetooth or USB cable.
ColorExpert is a full-featured colour management software with four
functional modules: My Colours, Colour Check, Colour Matching
System and Personal Centre.
In the 'My Colours' function module, users can collect or create
their own colour library from hundreds of other users' own shared
colour libraries. The PC software and mobile app can share accounts
and the colour library data follows the account to synchronise
information between PC and mobile.
In the 'Colour QC' function module, the user can calibrate, measure
and set up the spectrophotometer via the PC software. The user can
use colours from the cloud database as specimens to measure colour
differences, view spectrograms, colour difference graphs, specimen
trial data and export the desired data test reports.
The "Colour Matching System" function module provides the user with
a more convenient and efficient colour matching process. After the
colour of the sample has been measured by the instrument, the
system calculates the recipe in the recipe centre and automatically
fixes the colour to achieve an accurate match. The system is
suitable for computerised automatic colour matching applications in
the paint, coating, printing and textile industries.
The 'Personal Centre' function allows users to edit their personal
information, search for or delete connected instruments, manage
downstream users and manage the colour library shared with
downstream users.
