? 933N Is a variable wavelength adjustment type fluorescence spectrophotometer, excitation wavelength standard 365nm The emission wavelength range. 360-650nm The spectral bandwidth. 12NM , 4 LED Data display, Four A button to complete the fluorescence value and function expansion, concentration and concentration factor set operation.
??????? 930N Fluorescence spectrophotometer with RS232 The communication port for distribution and general data processing software package for on-line operation, more convenient for you to calculate and process the data further, save the operating time of your. Can also be used for external serial printer printout, convenient data storage.
The instrument is widely used for quantitative and qualitative analysis in biochemistry, food, environmental protection, chemical industry and other departments, is an ideal instrument for the school laboratory, factory testing and selection.
Characteristic：
The emission monochromator used One thousand and two hundred Line grating, large aperture aspheric mirrors, especially high sensitivity.
High brightness, long life LED The light source, to ensure the high stability test.
The new design of the sample pool frame, ensure the test method of diversification.
The high performance photoelectric multiplier tube, which can obtain the best signal to noise ratio.
The auto zero, automatic background subtraction.
The eight section sensitivity adjustment.
The real-time fluorescence value, concentration print.
The single point sample concentration direct reading test function.
With the data processing software package can be more general standard linear regression.
The fluorescence value of ultra wide dynamic range, small changes in accurate determination of sample.
