752N UV-VIS / 722N VIS Spectrophotometer

752N UV-VIS / 722N VIS Spectrophotometer

Visible/UV-Vis Spectrophotometer ,  200-1000nm/325-1000nm/360-1000nm

Description

Detailed introduction

The product uses microprocessor control technology to qualitatively and quantitatively analyze substances in the UV-visible region. It is an essential multi-purpose analytical instrument for routine laboratories.

Main feature:

  • Holographic blazed grating monochromator with high wavelength accuracy, good monochromaticity and low stray light.
  • 7-inch color touch screen, good human-computer interface.
  • The concentration test method increases the linear regression method and the coefficient method.
  • Added USB interface, large capacity memory can store 30 concentration curves.
  • With microcomputer measurement system, T-A conversion has high precision, and has automatic adjustment of 0%T and adjustment of 100%T, concentration factor setting and concentration direct reading.
  • Measurement readings are accurate, reproducible and stable.
