## Features

- 【High Accurate Measurement】 - The visible spectrophotometer uses imported tungsten filament lamps and high-sensitivity photoelectric converters, so it can ensure that there is minimal error in measuring wavelength and transmittance, thereby achieving accurate and stable measurement results.
- 【High Technology】- This 721N type spectrophotometer adopts microcomputer processing technology, which is suitable for material determination and quantitative analysis in visible spectroscopy field. Wavelength range: 350-1020mm; Wavelength accuracy: ±2nm;Spectral bandwidth: 6nm
- 【Auto Function】- The spectrometer has automatic wavelength adjustment function and automatic data storage function. In addition, the ultraviolet spectrometer has an automatic light gate function, which can easily capture the required light waves. It can also automatically reset the data to zero to make the data results more accurate and improve the accuracy of the test.
- 【Large Sample Chamber】 - The visible spectrophotometer possess a large sample chamber, which can be equipped with 100mm cuvette frame
- 【Wide Application】- The spectrometer is one of the commonly used analytical instruments in physical and chemical laboratories, widely used in many fields such as medical testing, food, petrochemical industry, environmental protection and monitoring.
