723A Visible spectrophotometerDetailed product description：

1、 Product Description:

The 723A visible light spectrophotometer has multiple complex functions of a large advanced instrument. It can meet the qualitative and quantitative testing requirements of the vast majority of samples in conventional laboratories.

2、 Characteristics:
1. Using microcomputer technology, it has the function of automatically adjusting 0% T and 100% T, which can directly eliminate the pairing error of colorimetric dishes.
2. The measurement reading has high accuracy, good reproducibility and stability.
3. There are advanced functions such as concentration direct reading, linear regression, timed printing, GOTO λ, and spectral scanning, and specialized functions can also be added according to user needs.
4. There are various conventional colorimetric dishes and semi micro colorimetric dishes available, as well as optional accessories such as micro automatic constant temperature pools.
5. You can choose to output to a printer or PC standard (RS232) interface.
