752N UV Visible SpectrophotometerDetailed product description：

752N UV visible spectrophotometer

1、 Basic principle:

The spectrophotometer analysis method is based on the selective absorption of electromagnetic radiation by substances with different molecular structures.
The visible spectrophotometer is usually used in the range of 200nm to 800nm for the application of electromagnetic radiation spectrum.

2、 Characteristics:

1. Adopting advanced holographic scintillation grating monochromator, it has the advantages of high wavelength accuracy, good monochromaticity, and low stray light.
2. Adopting a microcomputer measurement system, the T-A conversion accuracy is high, and it can be automatically adjusted to 0% T and 100% T, with concentration factor setting, concentration direct reading, and serial selection
The data printer performs data printing function.
3. The measurement reading has high accuracy, good reproducibility and stability. Optional printer.
