Array Spectrophotometer ST700D Plus

Introduction:

The ST700D Plus is an advanced array spectrophotometer developed by 3nh, utilizing its proprietary spectroscopic core technology. It features a built-in silicon photodiode array (40 sets of dual columns) sensors and an industrial-grade MCU. The powerful data processing capability ensures stability and accuracy, with the repeatability ΔE*ab controlled within 0.02 and inter-instrument error ΔE*ab within 0.18. This spectrophotometer is designed for precise color measurement in various applications, supported by a large-size touch screen for easy and convenient viewing of measurement results.

The ST700D Plus is equipped with five measurement apertures: Ø8 mm (flat and tip), Ø4 mm (flat and tip) and 1 × 3 mm. It provides versatile, accurate color measurement across industries such as plastics, electronics, paints and coatings, textiles, printing, automotive, medical care, cosmetics, food, scientific research, and laboratories.

Features of the ST700D Plus:

  • Silicon Photodiode Array Sensor: Equipped with dual 40 array sensors, it offers high sensitivity under weak light, a wide spectral response range, and superior measurement speed, accuracy, and stability.
  • Full-Band Balanced LED Light Source: Uses a 360~780nm full-band balanced LED light source and UV light source for accurate measurements, including fluorescent materials.
  • Grating Spectroscopic Technology: Provides high-resolution color measurement.
  • Non-contact Automatic Whiteboard Calibration: Includes an intelligent calibration base for accurate, repeatable data.
  • Ergonomic Design: Large touch screen and well-positioned controls for user comfort.
  • Five Measuring Apertures: Ø8mm and Ø4mm in flat and tip versions, plus 1x3mm, for flat, curved and small samples.
  • Camera Framing Positioning: Built-in camera for accurate measurement area targeting.
  • Excellent Repeatability and Inter-instrument Error: Ensures consistent data across devices, ideal for color matching.
  • Multiple Color Measurement Spaces and Light Sources: Supports a wide range of color spaces and light sources, customizable to specific needs.
  • Internationally Universal D/8 SCI/SCE Synthesis Technology: Provides objective color measurement, minimizing surface texture effects.
  • Dual Optical Path System: Offers precise color measurement, including SCI and SCE spectra.
  • Multi-Platform Support: Compatible with Android, IOS, Windows, WeChat Applets, and Harmony OS for comprehensive data management.
