Part 1. Benchtop Spectrophotometer Introduction
CS-820N is an smart, simple operate and high precise
spectrophotometer. It adopts 7 inches touch screen, full wavelength
range, Android operate system. Illumination : reflectance D/8° and
transmittance D/0°(UV included / UV excluded), high accuracy for
color measurement, large storage memory, PC software, because of
above advantages, it is used in laboratory for color analysis and
communication.

Part 3. Benchtop Spectrophotometer Advantages
1). Adopts reflectance D/8° and transmittance D/0° geometry to
measure both opaque and transparent materials.
2). Dual Optical Paths Spectrum Analysis Technology
This technology can simultaneous access to both measurement and
instrument internal environmental reference data to ensure
instrument accuracy and long-term stability.
3). Compatible with SCI/SCE measurement, Support SCI+SCE
Measurement
Instrument adopts D/8 geometry which is highly recommends by CIE
(International Commission on Illumination) to meet color
measurement of different industries. It supports both SCI (specula
component included) and SCE (specular component excluded) mode for
better detect of color change. Fast SCI+SCE measurement, test time
only need less than 4s.
4). Rotatable Touch Screen with Android Operate System
Screen position and direction can be adjusted according to the
instrument test methods.
5). Open Transmittance Measurement Area, no limit on sample size
6). Different Kinds of Accessories for simple measurement
It contains 15 kinds of standard and 12 kinds of optional
accessories to measure different kinds of materials
7). Accessory Drawer to Protect and Store Accessories
8). Switchable Reflectance Apertures (30mm,18mm,11mm and 6mm)
9). Four Kinds of UV Test Modes for Fluorescence Material
Measurement
