The 721G visible spectrophotometer can be widely used in biological research, biotechnology, drug analysis, pharmaceuticals, historical research, environmental protection, food hygiene, and other fields. It is controlled by a single-chip microcomputer, equipped with a back, clinical testing, and health and epidemic prevention.

Performance characteristics
▲ Adopting single-chip microcomputer control, with backlight 4-digit LCD display
▲ Automatic 0% to 100% adjustment function and error free T-A conversion
▲ Wide sample pool (maximum optional 100mm colorimetric dish)
▲ Adopting a C-T monochromator optical path system with low stray light and high resolution. And equipped with high-performance sparkling holographic gratings, it has excellent optical accuracy, measurement accuracy, reproducibility, and stability.
▲ It has 4 measurement modes: transmittance (T), absorbance (A), concentration direct reading, and coefficient determination (F), which meet the testing requirements
Equipped with RS232 interface, it can connect to a printer to print and output measurement data. It can be controlled by a PC to achieve more accurate and flexible measurement requirements (optional)
