Array Spectrophotometer ST-700d Plus with 5 Apertures

ST-700d Plus 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 Plus can easily control the repeatability ΔE*ab within 0.02, and the inter-instrument error ΔE*ab within 0.18. 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 Plus is equipped with five measurement apertures : Φ8mm (platform + tip), Φ4mm (platform + tip), 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 Plus

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 Plus adopts 360~780nm 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 Plus 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 five measuring apertures to meet the needs of more sample measurement

The array spectrophotometer ST-700d Plus is equipped with Ø8mm platform aperture, Ø8mm tip aperture, Ø4mm platform aperture, Ø4mm tip 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 Plus 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≤0.02, inter-instrument error ΔE*ab≤0.18, 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, F7(DLF), F8, F9, F10(TPL5), F11(TL84), F12(TL83/U30), B, U35, NBF, ID50, ID65, LED-B1, LED-B2, LED-B3, LED-B4, LED-B5, LED-BH1, LED-RGB1, LED-V1, LED-V2, LED-C2, LED-C3, LED-C5. The light source 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 Plus 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.
