Visible Spectrum Spectrophotometer

Feature
• Guided Procedure: The DR 3900 guides you step-by-step through the testing procedure like a GPS, so you can get the accurate results you need every time.
 
• Elimination of False Readings: Scratched, flawed, or dirty glassware becomes a non-issue when your machine takes 10 readings and eliminates outliers.
 
• Flexible Connectivity: Built with 1 ethernet and 3 USB ports, the DR 3900 easily connects to your computer and is programmed to easily interface with Hach WIMS™ or any LIMS system.
 
Includes: Adapter A for 1 in. round and 1 cm square cells, matched pair of 1 in. square glass sample cells, light shield, dust cover, printed basic user manual, full user manual and procedures on CD, and benchtop power supply with 115 and 230V power cords.
