Audited Supplier 8mm Aperture Spectrophotometer ST1818 ISO7724-1 Colorimeter for Cosmetics Color Difference Values
INTRODUCTION
ST1818 is a new portable spectrophotometer with 3nh own core research and development technology,Built-in large area silicon photodiode array (double row 18 groups) sensors, with excellent repeatability and inter-station differences, measuring data continued stable, accurate and reliable. The repeatability ΔE * AB of the array spectrometer ST1818 is easily controlled within 0.038, and the Inter-instrument Error ΔE * AB is controlled within 0.38. The measurement is accurate and can be used for accurate color analysis and transmission in the laboratory.
ST1818 array spectrometer with Φ8MM/φ10mm platform + Φ8MM/φ10mm sharp tip two measuring aperture, no matter the sample surface is regular flat or curved radian, can easily measure and get reliable and good repeatability data, in plastic electronics, paint coating, textile printing and dyeing, printing paper products, automotive, medical, cosmetics and food industries, scientific research institutions, laboratories are widely used.
Characteristics of the array spectrometer ST1818
1. Silicon photodiode array (18 double-row) sensors
The larger array sensor, the stronger light will not be saturated, the lower light sensitivity is higher and the wider spectrum response range, has guaranteed the instrument measurement speed, the accuracy, the stability and the consistency, grasps the core technology, with the same platform of international standards, achieve perfect compatibility.
2,Adopt full waveband balanced LED light source
The array spectrometer ST1818 adopts 400 ~ 700nm full waveband balanced LED and UV light source as the illumination light source, which has enough spectrum distribution in the visible light range and avoids the loss of the spectrum of white LED in the specific wave band,Fluorescent materials can also be easily measured.
3,Grating Spectroscopic Technology
The use of plane grating spectroscopy technology, with a higher resolution, so that more accurate color measurement.
4,Intelligent base, automatic calibration
It is equipped with intelligent calibration base, can carry out automatic white board calibration, professional grade standard white board reflectivity R% ≥95% , good surface uniformity, high stability, can obtain repeated accurate data.
5,New fashion appearance design based on ergonomics
The hand-held position and the position of the measuring button are carefully designed to meet different holding habits, smooth and fine surface, derived from the professional appearance treatment technology.
6, Excellent interstation and repeatability
The repeatability ΔE * ab ≤0.038, the Inter-instrument Error ΔE * AB ≤0.38 data is stable and reliable, which ensures the consistency of the data measured by multiple devices, and can be used for color matching and accurate color transfer.
7,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.
8,Double light path system is more stable in color measurement
Double optical path system, when the environment changes, to ensure that the measurement data more stable and accurate.
9,Color management software
The array spectrometer ST1818 is equipped with SQCX software, which is suitable for quality monitoring and color data management in various industries. The user's color management data, compare color differences, generate test reports, provide a variety of color space measurement data, customized customer color management.
