The DR 3800 is a VIS spectrophotometer with a wavelength range from 320 to 1100 nm. The instrument comes with a complete set of application programs and supports multiple languages. The DR 3800 spectrophotometer includes the following


Programs and operating modes:
Stored Programs (pre-installed tests), Barcode Programs, User Programs, Favorites, Single Wavelength, Multi-Wavelength, Wavelength Scan, and Time Scan.
The DR 3800 Spectrophotometer performs digital measurements in units of concentration, absorbance, or % transmittance.
When a user-generated or programmed procedure is selected, a structured menu system and prompts guide the user through the test. This menu system can also generate reports, statistical evaluations of generated calibration curves, and reports on instrument diagnostic tests.
