Features of DR 3900
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 Results Scratched, flawed, or dirty glassware becomes a non-issue when your machine takes 10 readings and eliminates any outliers.
Hands Free Updates RFID* technology automatically updates the program's calibration factors when you place a TNTplusTM chemistry box near the machine.
Flexible Connectivity Built with 1 LAN and 3 USB ports, the DR 3900 easily connects to your computer and is programmed to easily interface with a LIMS system.
Sample Tracking (Feature coming soon!) Sample bottles with smart tags can easily be tracked with the new Hach RFID* sample-ID system, eliminating sample mix-ups and providing better sample traceability.
