Array Spectrophotometer ST-700d with 3 Apertures
ST-700d is an array spectrophotometer developed by 3nh using its
own spectroscopic core technology. It uses a built-in silicon
photodiode array (40 sets of dual columns) sensors and an
industrial-grade MCU. The powerful data processing capability
ensures the stability and accuracy of the measurement data. The
array spectrophotometer ST-700d can easily control the
repeatability ΔE*ab within 0.022, and the inter-instrument error
ΔE*ab within 0.2. It can be used for accurate color measurement in
various occasions and conditions, and the large-size touch screen
can view the measurement results more easily and convenient. The
measurement data of the instrument is consistent with other
competing products from Japan, the United States, and Europe.
The array spectrophotometer ST-700d is equipped with three
measurement apertures : Φ8mm, Φ4mm, and 1x3mm. It has wider
adaptability, accurate color measurement and stable performance. It
is used in plastic electronics, paint and coatings, textile
printing and dyeing, printed paper products, automobiles, medical
care, cosmetics and food industries, and also are widely used in
scientific research institutions and laboratories.

Features of Array Spectrophotometer ST-700d
1,Silicon photodiode array (dual 40 array) sensor
Larger area dual 40 array sensor, will not be saturated under
strong light, sensitivity is higher under weak light, and the
spectrum response range is wider, which ensures the measurement
speed, accuracy, stability and consistency of the instrument.
Master the core technology, developed from same platform as
international standards with full compatibility.
2,Adopt Full-band balanced LED light source + UV light source
The array spectrophotometer ST-700d adopts 400~700nm full-band
balanced LED light source and UV light source as the instrument
lighting source, which has sufficient spectral distribution in the
visible light range, avoiding the spectrum lack of white light LED
in specific bands. It can also easily measure fluorescent materials
and ensures the accuracy of the instrument measurement results.
3,Grating Spectroscopic Technology
Adopting plane grating spectroscopic technology, it has higher
resolution and makes color measurement more accurate.
4,Non-contact automatic whiteboard Calibration
The array spectrophotometer ST-700d is equipped with an intelligent
calibration base, which can be used for non-contact automatic
whiteboard calibration. The professional-grade standard whiteboard
reflectance R%≥95% has good surface uniformity and high stability,
and can obtain repeatable and accurate data.

5,Novel fashion design based on ergonomics
The large-size touch screen is more convenient to check the
measurement results and color judgment. The position of the hand
grip and the measurement button are carefully designed to meet
different grip habits. The smooth and fine surface is derived from
the high-precision appearance processing art.
6,Equipped with three measuring apertures to meet the needs of more sample measurement
The array spectrophotometer ST-700d is equipped with Ø8mm platform
aperture, Ø4mm platform aperture, and 1x3mm aperture as standard
accessory, which meets the measurement needs of most special
samples.

7,Camera framing positioning can clearly observe the measured area
The array spectrophotometer ST-700d has a built-in camera for
viewing and positioning. Through the real-time viewing of the
camera, it can accurately determine whether the measured part of
the object is at the center of the target, which improves the
measurement efficiency and accuracy.
8,Excellent inter-instrument Error and repeatability
Repeatability ΔE*ab≤0.022, inter-instrument error ΔE*ab≤0.2, the
data is stable and reliable, ensuring the consistency of
measurement data of multiple devices, which can be used for color
matching and accurate color transfer.
9,Multiple Color Measurement Spaces and Observation Light Sources
Provide CIE LAB, XYZ, Yxy, LCh, CIE LUV, s-RGB, HunterLab, βxy, DIN
Lab99, Munsell(C/2) color spaces, and multiple observation light
sources: D65, A, C, D50, D55, D75, F1, F2(CWF), F3, F4, F5, F6,

can be customized (a total of 41 kinds of light sources, some of
which are realized through the host computer/APP), which can meet
the special measurement requirements under different measurement
conditions.
10,Using the Internationally Universal D/8 SCI/SCE Synthesis Technology
Use D/8 (SCI/SCE) to measure the structure, reflect the color
itself more objectively, reduce the influence of the surface
texture of the object on the test result, and meet the standards:
CIE No.15,GB/T 3978, GB 2893, GB/T 18833, ISO7724-1, ASTM E1164,
DIN5033 Teil7.
11,Dual Optical Path System for More Accurate Color Measurement
Dual optical path system, the optical resolution in the visible
light range is less than 10nm, and can measure the SCI and SCE
spectra of samples at the same time.
12,Support Android, IOS, Windows, WeChat Applet, Harmony OS.
The array spectrophotometer ST-700d supports Android, IOS, Windows,
WeChat applets, and Harmony OS, and is suitable for quality
monitoring and color data management in various industries. Codify
the user's color management with data, compare color differences,
generate test reports, provide a variety of color space measurement
data, and customize the customer's color management work.
