Instrument Introduction:
The 725S visible spectrophotometer is a new generation of miniaturized instrument, which adopts a 128 × 64 dot matrix 3-inch LCD display, Chinese menu and online status prompts, with more friendly and clear operation and error message display to improve human-computer interaction ability. This instrument can directly use the least squares method for calibration, with an internal 2K power-off protection memory that can save multiple test parameter files. It is easy to use and can perform data processing such as statistics, analysis, and tabulation.

Instrument usage:
The 725S visible spectrophotometer is easy to use and has complete single machine operation functions. It is the best choice for qualitative and quantitative analysis in medical and health, clinical testing, biochemistry, petrochemicals, environmental monitoring, quality control and other departments!
