Specification
Brand : HOJILA
BulletPoint1 : 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
BulletPoint2 : 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
BulletPoint3 : 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
BulletPoint4 : 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
BulletPoint5 : 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
BulletPoint6 : 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
BulletPoint7 : 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
