3nh portable colorimetro dental spectrophotometer d/8 with 4mm
small aperture NS820
3nh NS820 spectrophotometer uses d/8 structure and comply with CIE
No.15, GB/T 3978. With 400~700nm, NS820 features with high accuracy
DeltaE*ab 0.04, and 4mm 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.
NS820 is a model of spectrophotometer with incomparable accuracy.
It features a 4mm aperture and a ultra-large integrating sphere
which can evenly distribute light more effectively, which makes the
measurement results more accurate.
The errors of the absolute values of L*ab of the spectrophotometers
from USA, Germany and Japan are all ±1.5, while, after careful
comparison, the error of L*ab absolute value of our NS series
spectrophotometer is only ±1.0.
It is configured with two observer angles, multiple light source
types, multiple color space systems and color difference formulas,
all of which have endowed NS series spectrophotometer with powerful
functions to meet the requests of all kinds of color measurements.
The large touch-screen display makes operation more friendly. And
once connected with PC via the software SQC8, more extension
functions will be at hand.
