Product Description

CS-820N High precision Bench-top touch screen control UV Spectrophotometer   CS-820N High precision Bench-top touch screen control UV Spectrophotometer   CS-820N High precision Bench-top touch screen control UV Spectrophotometer  

The desktop spectrophotometer CS-820N is an intelligent, convenient and precise spectrophotometer, using TFT true color 7-inch capacitive touch screen, full spectrum, and Android operating system. Illumination mode: reflection D/8°, transmission D/0° (including UV/excluding UV measurement), accurate and stable measurement color, large storage capacity, powerful expansion functions on the PC side, for laboratory color analysis and transmission.


1. Transmissive D/0 structure and reflective D/8 structure.

2. Dual optical path spectrum analysis technology

It can simultaneously obtain the measurement sample and the internal environment reference data to ensure the accuracy and long-term stability of the instrument measurement.

3. Compatible with SCI/SCE measurement, and support SCI+SCE simultaneous rapid measurement

Adopt the D/8 illumination observation conditions recommended by the International Commission of Illumination to meet the measurement needs of various industries; it can perform specular reflection (SCI) and specular reflection (SCE) measurements, and more fully insight into color data changes. And it supports SCI+SCE rapid measurement at the same time, and the test time is less than 4 seconds.

4. Configure Android operating system and rotatable capacitive touch screen

The instrument APP based on the Android operating system and the 7-inch large touch screen are as smooth and convenient as the daily operation of a mobile phone, and it is easier to operate.

5. Open transmission sample compartment, containing large size samples

The open transmission sample compartment is not limited by the sample size, and even large-sized films can be easily handled.

6. Abundant accessories

15 kinds of standard accessories, 12 kinds of optional accessories, to meet the testing needs of different scenarios.

7. The instrument has its own accessory drawer, which is convenient for accessory protection and storage

8. The reflection measurement caliber can be switched

With four measuring apertures, the instrument automatically recognizes the aperture and adjusts the light path, bid farewell to manual.

9. Four types of UV measurement modes make the fluorescence invisible
