UV Visible Spectrometer
Description:
The 752N Plus UV visible spectrophotometer uses microprocessor control technology to perform qualitative and quantitative analysis of substances in the UV visible spectral region, and is a versatile analytical instrument required for routine laboratories.
Main features:
Holographic glitter grating monochromator has the advantages of high wavelength accuracy, good monochromaticity, and low stray light.
Adopting a 7-inch color touch screen with a good human-computer interaction interface.
The concentration testing methods include linear regression and coefficient methods.
Equipped with a USB interface, the large capacity memory can store 30 concentration curves each.
Adopting a microcomputer measurement system, the T-A conversion accuracy is high, and it has automatic adjustment of 0% T and 100% T, 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.
It has functions such as dynamic time scanning, time setting, and multiple language switching.
