Expert water analysis made simple.

Prevent Measurement Errors…Simply

Built with the future of water analysis in mind, the DR3900 Spectrophotometer will give consistently accurate results in a simpler testing format.LPV440.99.00002

This instrument connects to Claros, innovative Water Intelligence System, enabling you to seamlessly connect and manage instruments, data, and process – anywhere, anytime. The result is greater confidence in your data and improved efficiency in your operations.

Simple Preparation

TNTplus vials use DosiCaps that are easier to use than Powder Pillows or Liquid Reagents, without any risk of contamination.
The boxes and vials are color-coded for fast and easy parameter and range recognition of exactly the test you need.
Step-by-step illustrated test methods are printed on the box as quick reference or can be called up in the instrument menu.

Fast execution

A 2D barcode on the TNTplus vial is automatically read by the Hach DR spectrophotometer to identify the appropriate method and take the measurement. The vial spins to take 10-fold absorbance readings that will be averaged for result determination to exclude scratches and fingerprints. Instrument calibration verification and high instrument stability all combine to eliminate the need to run reagent blanks.
