Features

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.

Comprehensive Documentation

Measurement results are documented on the detailed level with timestamp, operator ID, absorbance reading, and calculated concentration. The 2D barcode delivers the lot number and expiry date, logged with every result.

*RFID technology currently available in the US, Puerto Rico, Austrailia, New Zealand, and Colombia only.

Customizable

With the ability to store hundreds of user-determined methods, operators are able to tailor the DR3900 to meet the everyday needs of the plant.
Being able to optimize and customize the method portfolio, combined with regular software updates and Claros connectivity, makes the DR3900 the ultimate solution to water quality lab needs.
