Audited Supplier 3nh Portable Digital Spectrophotometer ST-700D Three Apertures Blackness Tint Testing Machine
INTRODUCTION
Portable Digital Spectrophotometer ST-700D Three Apertures Blackness Tint Testing Machine is an array spectrophotometer developed by 3nh using its own spectroscopic core technology. It uses a built-in silicon photodiode array (40 sets of dual columns) sensors and an industrial-grade MCU. The powerful data processing capability ensures the stability and accuracy of the measurement data. The array spectrophotometer ST-700d can easily control the repeatability ΔE*ab within 0.022, and the inter-instrument error ΔE*ab within 0.2. It can be used for accurate color measurement in various occasions and conditions, and the large-size touch screen can view the measurement results more easily and convenient. The measurement data of the instrument is consistent with other competing products from Japan, the United States, and Europe.
The array spectrophotometer ST-700d is equipped with three measurement apertures : Φ8mm, Φ4mm, and 1x3mm. It has wider adaptability, accurate color measurement and stable performance. It is used in plastic electronics, paint and coatings, textile printing and dyeing, printed paper products, automobiles, medical care, cosmetics and food industries, and also are widely used in scientific research institutions and laboratories.
Features of Array Spectrophotometer ST-700d
1,Silicon photodiode array (dual 40 array) sensor
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. Master the core technology, developed from same platform as international standards with full compatibility.
2,Adopt Full-band balanced LED light source + UV light source
The array 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.
3,Grating Spectroscopic Technology
Adopting plane grating spectroscopic technology, it has higher resolution and makes color measurement more accurate.
4,Non-contact automatic whiteboard Calibration
The array 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.
5,Novel fashion design based on ergonomics
The large-size touch screen is more convenient to check the measurement results and color judgment. The position of the hand grip and the measurement button are carefully designed to meet different grip habits. The smooth and fine surface is derived from the high-precision appearance processing art.
