- Quick and Accurate: More than 220 pre-programmed methods with easy reagent recognition.
- Guided Procedures: Step-by-step guides ensure consistent results.
- Enhanced Accuracy: Utilizes RFID technology and TNTplus test kits.
- High-Speed Scanning: Covers visible spectrum (320 - 1100 nm).
Product Advantages
Simple Preparation
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.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.
For your accreditation the certificate of analysis can be called up just by wiping the reagent box towards the RFID* sensor.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.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 Smart Monitoring, makes the DR3900 the ultimate solution to water quality lab needs.
