Prevent measurement errors...simply.

The proven technology you have come to expect from Hach just got better. Built with the future of water analysis in mind,
the DR 3900 will give consistently accurate results in a simpler testing format.

Guided Procedure Flexible Connectivity

The DR 3900 guides you step-by-step through the testing Built with 1 ethernet and 3 USB ports, the DR 3900 easily
procedure like a GPS, so you can get the accurate results connects to your computer and is programmed to easily
you need every time. interface with Hach WIMS™ or any LIMS system.
Elimination of False Readings Sample Tracking*
Scratched, flawed, or dirty glassware becomes a non-issue Sample bottles with smart tags can easily be tracked with
when your machine takes 10 readings and eliminates outliers. the optional Hach RFID sample-ID system, eliminating sample
mix-ups and providing better sample traceability.
Hands Free Updates*
RFID technology automatically updates the program calibration
factors when you place a TNTplus box near the machine. *RFID technology currently available in US,
Canada, Austrailia, and New Zealand only.
