A unique barcode label on each Hach TNTplus Vial Chemistry is automatically read by the spectrophotometer when used with Hach's DR spectrophotometers to identify the appropriate method and take the measurement. While increasing ease-of-use and speed of analysis, potential errors are significantly reduced.
The high quality of TNTplus vials, tight reagent production controls, 10-fold absorbance readings averaged for results determination, instrument calibration verification, and high instrument stability all combine to eliminate the need to run reagent blanks—saving you time and money!
New features have been added to the vial barcode, allowing the spectrophotometer to detect the reagent lot number and expiration date—notifying the user if reagents are expired. Using a DR3900 or DR6000 equipped with the RFID feature, an RFID tag on the package triggers any required method calibration updates simply by placing the box adjacent to the instrument.
