Description

N4 Ultraviolet Visible Spectrophotometer

 

Products Details:

N4 Ultraviolet Visible Spectrophotometer, combined with arm processing core, automatic wavelength makes the instrument have the test speed and function of high quality instrument. It can meet the requirements of qualitative and quantitative analysis of most samples in UV-Vis spectrum range in conventional laboratory. It is suitable for medical and health, clinical laboratory, biochemistry, petrochemical, environmental protection, quality control and colleges and universities.

 

Main Features:

1.7-inch color touch screen and patented technology can realize concise and effective human-computer interaction, and clearly display test data and scanning results. 

2.USB communication port and uvwin8 UV spectrum software are selected to realize the processing function of data and spectrum, as well as the storage of massive data documents, and provide convenience for the secondary development of customers.

3. It has the functions of dynamic time scanning, automatic wavelength, linear regression, concentration direct reading, peak valley detection, timing printing, etc. 

4.The advanced power-off protection measures can memorize the test data, regression equation and instrument correction parameters to realize rapid initialization. 

5.It has the life protection function of halogen tungsten lamp and deuterium lamp.

6.Automatic light door technology, no need for blackbody, protect photoelectric sensor.
