产品描述
723N type spectrophotometer is smart products, combined with single-chip microcomputer control technology, the instrument has a large variety of advanced equipment of the complex function, can meet the general laboratory most samples of qualitative and quantitative test requirements. Widely used in medicine and health, clinical examination, biochemistry, petroleum chemical industry, environmental protection, quality control and other departments. The instrument of high performance and low price, is your best choice.
Main features:
The instrument adopts 5 LCD graphic display and external thermal printer as the display and output devices, clearly display the test results and operation tips, thermal printer can conveniently print data report and test results were saved.
The test method provides a photometric model, wave scanning, quantitative analysis, dynamic analysis and multi wavelength test mode, input coefficient, one point method and multi-point pending three kinds of commonly used analytical methods in quantitative test mode.
Unique cuvette pairing function can eliminate the measurement error caused by comparison cuvette pairing (only valid and quantitative analysis model in spectrophotometry).
Having automatic zero adjustment and full function of /.
The measurement of high accuracy, good reproducibility and stability.
We have direct reading, linear regression, time print, GOTO and other senior lambda spectral scanning function
