DR 3900™ Spectrophotometer

Description

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

 

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.

 

 

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.

 

 

Elimination of False Readings

 

Scratched, flawed, or dirty glassware becomes a non-issue when your machine takes 10 readings and eliminates outliers.

 

Hands Free Updates*

 

RFID technology automatically updates the program calibration factors when you place a TNTplus box near the machine.

 

 

Sample Tracking*

 

Sample bottles with smart tags can easily be tracked with the optional Hach RFID sample-ID system, eliminating sample mix-ups and providing better sample traceability.

 

 

*RFID technology currently available in US,

 

Canada, Austrailia, and New Zealand only.
