Purpose

This instrument can measure the absorption spectrum of substances in the visible spectrum range, and conduct qualitative and quantitative analysis of sample substances or components and contents. It is widely used in medicine, health, food, chemistry, biology, environmental protection and other fields. One of the most commonly used instruments in scientific research.

Features

Model 722 visible spectrophotometer adopts low stray light, high resolution monochromatic light path structure, and the instrument has good stability and reproducibility. The application of microcomputer processing technology makes the operation more convenient, and the test can be completed with a few buttons, and it has the control functions such as automatic adjustment of 0%T and 100%T and the data processing function of various methods.

The LED digital display can display parameters such as transmittance, absorbance and concentration, which improves the reading accuracy of the instrument.

Print output, equipped with a serial port, can be directly connected to a printer to print test data.
