Features
The optical system design and circuit control system design of the HZ1902 dual-beam UV-Vis spectrophotometer is very rigorous, the selection of components is strictly controlled, and it has high standards of accuracy, repeatability, low noise and low stray light indicators, linear range and stability The indicators are also very good. 2nm bandwidth, large-screen LCD display, high measurement accuracy and stability, is a high-quality instrument.
The HZ1902 dual-beam UV-Vis spectrophotometer uses Hamamatsu's ozone-free environmentally friendly deuterium lamp, with a service life of 2000 hours, and the light output can remain stable until its service life, and it is extremely convenient to replace.
HZ1902 dual-beam UV-Vis spectrophotometer provides 2 operation modes: host measurement mode or software control measurement mode.
The built-in SCM technology and qualitative and quantitative analysis software can realize extended functions such as data acquisition and processing, spectral measurement, kinetic measurement, quantitative analysis, DNA measurement and spectral scanning. The menu pull-down analysis software is easy to operate.
The HZ1902 dual-beam UV-Vis spectrophotometer has an open sample chamber, and can be equipped with reflective sample holders, solid sample holders, constant temperature water baths and autosamplers for different applications.
9 scan curves can be stored in a single machine, and 9 working curves can be stored. There is no limit to the number of online storages.
