TNTplus vials use DosiCaps - freeze-dried reagents integrated into sealed cap - that are easier to use than Powder Pillows or Liquid Reagents, without any risk of contamination.
The boxes and vials are color-coded for a 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 a quick reference and can also be called up in the instrument menu.
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.
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.
For your accreditation the certificate of analysis can be called up just by wiping the reagent box towards the RFID* sensor.
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.
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.
