en-Hach DR 3800 VIS Spectrophotometer

The DR 3800 is a VIS spectrophotometer covering a wavelength range from 320 to 1100 nm. The unit comes with a comprehensive suite 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-defined programs, favorites, single wavelength, multi-wavelength, wavelength scan, and time scan.
The DR 3800 spectrophotometer performs digital measurements in the units of concentration, absorbance (extinction), or percent transmittance.
When choosing a user-generated or programmed method, a structured menu navigation and prompts guide the operator through the test procedure. This menu system can also generate reports, statistical evaluations of generated calibration curves, and equipment diagnostic reports.
