Visible Spectrophotometer
Description:
The 721 visible spectrophotometer adopts microprocessor control technology to perform qualitative and quantitative analysis of substances in the visible spectrum region, and is a multi-purpose analytical instrument required for conventional laboratories.
Main features:
Holographic glitter grating monochromator has the advantages of high wavelength accuracy, good monochromaticity, and low stray light.
Backlit LCD display to avoid reading errors caused by pointer display.
Adopting a microcomputer measurement system, the T-A conversion accuracy is high, and it has automatic 0% (T) and 100% (T) adjustment, concentration factor setting, and concentration direct reading.
The measurement reading has high accuracy, good reproducibility, and good stability.
Automatic light gate technology, no need for blackbody, protects photoelectric sensors.
