7230G visible spectrophotometer intelligent spectrophotometer

Description :

　　7230G visible spectrophotometer

　　It is a new generation of intelligent spectrophotometer with microcomputer, which has strong control function and data processing capability, and is equipped with printed output. It can be used for scientific research in physics, chemistry, medicine, biology, pharmacology and other disciplines, or for quantitative analysis of various substances in laboratories of chemical industry, food industry, pharmaceutical industry, metallurgical industry, clinical biochemistry, and environmental protection departments.

　　Main features of 7230G visible spectrophotometer:

　　Automatic zeroing, automatic full-scale adjustment, automatic establishment of linear equations, automatic switching of τ, A, C, and direct reading of concentration.

　　The sample room can accommodate 98mm colorimetric dishes, but an additional bracket is required.

　　Equipped with a convenient wavelength adjustment mechanism, there is no need to open the casing during adjustment.

　　The lamp source adopts a fixed voltage, and the sensitivity is automatically controlled by a microcomputer within the full wavelength range.
