JH754 UV Visible spectrophotometerFunctional features:
Adopting a 1200L/mm high-performance UV specific grating, imported long-life deuterium/tungsten lamps, imported photoelectric converters, and advanced C-T monochromator structure, the instrument has low stray light, high resolution, and good photometric linearity.
The spacious sample chamber can be expanded to a 10cm sample rack, thereby expanding the testing range of the instrument.
It has advanced functions such as automatic correction of wavelength errors and automatic switching of light sources, ensuring the testing accuracy and continuity of the instrument.
Adopting a 7-inch color Chinese/English touch screen display, it clearly and intuitively displays various data and spectra of the tested samples.
The instrument has functions such as photometry, quantification, and standard curve.

The 754 UV visible spectrophotometer can meet a wide range of application needs, from daily analysis to scientific research. The instrument adopts an advanced proportional dual beam optical path system and a low-noise circuit design, which has excellent reliability and stability.
