About this item
Expert water analysis made simple. Simplicity throughout: The Hach DR3900 photometer provides the simplest way to perform test for wateranalysis. Used together with TNTplus™ chemistries testing steps are reduced. The potential for human error is mininimized.
- Simple preparation
- Fast execution
- Comprehensive documentation
- Available with (or without) RFID for easy method update, sample ID and certificate of analysis
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.
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. For your accreditation the certificate of analysis can be called up just by wiping the reagent box towards the (optional) RFID sensor.
