Main features:
The use of advanced light, machine, electricity, micro computer die design fast, superior performance and price.
- the proportion of double beam optical structure, configuration and high performance "holographic gratings" low stray light high resolution monochromator has superior optical measurement precision and accuracy, reproducibility and stability.
Adopt the micro processing system operation function, automatic strong, test control and data processing, can automatically adjust the "special 0" 100 "eight" to adjust the sample pool linkage as well as light source mirror micro switch technology.
Having full wavelength scanning, multi band scanning ( 759S With time, the host type), and dynamic scanning GOTO. Linear regression, direct reading, peak detection and other advanced features.
Adopt the thermal plotter, data printing, scanning spectrum ( 759S The host has a fixed wavelength), rendering time scanning, linear regression curve.
- out A USB interface, can be directly with PC Machine interaction, strengthen the instrument test data, scan map processing function, realizes the test document mass storage, but also provides the convenience for users to develop two times.
Power off protection measures - reliable, memory data measured and scanning map, the regression equation and the instrument correction value, and realize the fast boot initialization enter test status.
The instrument is simple, users only need the corresponding LCD screen on the menu options and confirmation, which can achieve the desired function.
The instrument adopts the high energy long-life flange positioning of deuterium lamp. When the instrument of deuterium lamp must be replaced, only need to uninstall the two flange screws, to ensure that the light source is in the best position, without complicated optical adjustment.
