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.
