Description
Caltech India offers NS820 Small Aperture Spectrophotometer has the same specification with NS810 portable spectrophotometer, but this handheld spectrophotometer adopts 4mm aperture, fit for some special sample use, like printing logo.
NS820 d/8 handheld spectrophotometer machine with software uses d/8 structure and comply with CIE No.15, GB/T 3978. With 400~700nm, NS820 spectrophotometer features with high accuracy DeltaE*ab 0.04, and 8mm aperture makes measurement so easy. It can save 1000 Standards, 15000 Samples and you also can input your own LAB or XYZ value into the instrument.
With SQC8 software, you can do better color control management. Plus, it is widely used in plastic, electronic, paint, ink, textile, garment, printing and dyeing, food, medical, cosmetic, industries, scientific research institutes, schools and laboratories.
