Overview
The 760CRT dual beam UV visible spectrophotometer is an automatic recording spectrophotometer based on the Windows 7 platform. The interface is user-friendly, beautiful, and easy to operate. It can print analysis reports that combine text and images through a printer, and can transfer chart data or test data to Excel for processing. The chart can be pasted into Word for publication. The instrument has functions such as wavelength scanning, time scanning, quantitative analysis, fixed wavelength testing, and multi wavelength testing, which are suitable for daily analysis and research work in laboratories such as medicine, pharmacy, biochemistry, environmental protection, and chemical industry.
Product Details
1、 Main features:
1.Dual beam UV visible spectrophotometerAdopting holographic blazed grating, dual beam C-T optical path structure, high resolution, low stray light, high metering accuracy, and good stability performance.
2. Microcomputer control, automatic recording. The printer can print spectra, test data, and operating parameters on a single recording paper.
3. Automatic conversion of light source (can be set arbitrarily between 294nm and 364nm)
4. Spectral processing capability of function *.
2、 Software features:
1. Large information storage capacity and convenient storage.
2.Dual beam UV visible spectrophotometerThe software provides four spectral channels for temporary storage of spectra, allowing for coverage and overlap of transmittance, absorbance, absorbance logarithm, and energy spectrum scans. The spectra of transmittance and absorbance can be easily converted to each other, and the spectra can be subjected to arithmetic operations such as spectra and spectra, spectra and coefficients, and derivative operations.
3. Peak valley detection and scaling of the graph are easy and effortless.
4. Time scanning can be used for dynamic research.
5. Quantitative analysis provides concentration linear regression method, undetermined coefficient method and coefficient input method for curve fitting and outlier removal, as well as determination of 2 λ and 3 λ. 3 λ provides automatic wavelength setting and 10 sets of wavelength data for users to choose from.
6. The software provides fixed wavelength and multi wavelength testing, and can annotate the test data, making it convenient for multi-user testing of the same sample. Multi wavelength testing can perform up to 20 point wavelength tests.
7. It is easy to set the parameters of the stored spectrum to the current testing conditions of the instrument.
8. The printer can print parameters and graphs, parameters and graphs and data, parameters and data, and work curves.
