产品描述
The instrument:
As an upgraded version of the traditional 721, the design idea of 721S spectrophotometer in rich manufacturing experience, innovation and strict process management as a whole, mature standard combined with modern technology, the performance index of high quality, and can meet the measurement requirements of 100mm cuvette, is used for your content on the substance of the visible spectral region to carry out quantitative and qualitative analysis of quality brand instruments.
Use the instrument:?
721 spectrophotometer for the different needs of the field of research, teaching, monitoring or control of material content for users dedicated visible spectral region of the quantitative and qualitative analysis of the brand is the steel manufacturing, equipment, food inspection, environmental monitoring, college basic education laboratory and routine testing tools, electroplating, printing and dyeing, paper making the electric power industry.
* 4 18mm high brightness LED display.
I have 4 test modes: transmission ratio R, A, C and direct reading concentration absorbance coefficient setting F, fully meet the test requirements.
* wide measuring range: T model test scale range of 0-199.9% tau, A model test range for -0.300-1.999A.
Can improve the degree of automation: including automatic adjustment, automatic adjustment of 0 100%T and no T-A conversion error, so the test process is simple.
It is reasonable structure and advanced optical system design: the precision machining quality of C-T monochromator and sealed grating, the optical performance is better than the traditional LITTROW monochromator, has obvious advantages in resolution, photometric accuracy, stray light and stability index, and reduce the volume of.
This special precision presetting lamp and a lamp holder: no optical path adjustment again can replace the installation, provide convenience for the users do not have professional maintenance skills.
Precision linkage type cut-off filter system: it can automatically switch to the corresponding filter according to the wavelength, further reduce the stray light.
This sample chamber adopts special engineering plastics solvent and strong acid and alkali manufacturing, comprehensive corrosion, and effusion plate and liquid storage container from washing is added at the bottom, to improve the quality of user end instrument, is solved by the test conditions caused better solutions to shorten the life of instrument.
Using Lengguang technology standard sample chamber structure, with the common samples of the company 722S, S22PC, 752S and other types of equipment room accessories.
It has improved the cuvette lubrication degree and precision positioning.
* 4 pool structure: can use 10-50mm cuvette.
This flame retardant insulation plastic shell, safe use, small volume and light weight, and it has the advantages of beautiful appearance, it will hold transport shift, etc..
This instrument allows the power range extended from the traditional type 721 198-240V to 100-240V.
This manufacturing process to implement standardization, universal, consistent, the entire mold production process and tooling standard equipment, ISO9001/2000 system certification product quality full control, instrument quality guaranteed.
