Array Spectrophotometer ST-700D

Introduction:

The ST-700D 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 ?E*ab controlled within 0.02 and inter-instrument error ?E*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 ST-700d Plus is equipped with five measurement apertures: ?8mm (platform + tip), ?4mm (platform + tip), and 1x3mm. 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 Array Spectrophotometer ST-700d 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.
  • Multiple Measuring Apertures: Equipped with Ø8mm, Ø4mm, and 1x3mm apertures for various sample types.
  • 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.
