Drawell 722N VIS Spectrophotometer

Drawell 722N VIS Spectrophotometer

Product overview

The 722N VIS Spectrophotometer uses a Czerny-Turner monochromator, 1200 lines/mm grating and silicon photocell detector. Its 2 nm spectral bandwidth and low stray light support stable visible-light measurements across the 325–1100 nm range.

The Drawell 722N VIS Spectrophotometer supports research, pharmaceutical, environmental, food, industrial, and quality-control laboratories. Scientific China provides model selection, configuration review, export coordination, and formal quotations.

Key features

• 7-Inch Color Touchscreen: Clear, intuitive operation for routine measurements.
• 30 Concentration Curves: Supports curve storage, linear regression, coefficient methods and direct concentration readout.
• Automatic T/A & Zero Adjustment: Automatic T/A conversion plus 0%T/100%T adjustment reduces manual setup.
• 5–50 mm Cuvette Support: Accommodates different optical path lengths for various sample requirements.
• USB Interface: Enables convenient data connection and processing.
• Automatic Light Gate: Protects the photoelectric sensor without requiring a blackbody.
