Description

721N Visible Spectrophotometer

 

Product details:

721N Visible Spectrophotometer   uses microprocessor technology to make qualitative and quantitative analysis of substances in the visible spectrum region. It is a multi-purpose analytical instrument needed in the conventional laboratory.

 

 

Main features:

1.Holographic blazed grating monochromator has the advantages of high wavelength accuracy, good monochromaticity and low stray light.

2.Comfortable large screen with backlight LCD, the measurement data is clear at a glance.

3.The microcomputer measurement system has high precision of T-A conversion, automatic adjustment of 0% (T) and 100% (T), setting of concentration factor and direct reading of concentration.

4.The accuracy of the measurement is high, the repeatability is good and the stability is good.

5.Automatic light gate technology, no need for blackbody, protect photoelectric sensor.
