The DR3900 is a benchtop visible spectrum (320 - 1100 nm), split beam spectrophotometer with over 220 pre-programmed methods optimized for laboratory water analysis. With your daily routine of water analysis in mind, the DR3900 spectrophotometer is optimized for safe processes and accurate results. The DR3900 is designed to deliver accurate results quickly with Hach's innovative TNTplus® reagents, which are optimized around reduced handling steps, precise dosing, streamlined sample analysis, automatic test recognition, expiration date check, and more! Essential control parameters like Ammonium, COD, Phosphate, Nitrate and many others are easy to perform.


    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.

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

    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.

    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.


Includes: Spectrophotometer DR3900, adapter A for 1 in. round and 1 cm square cells, matched pair of 1 in. square glass sample cells, light shield, dust cover, printed basic user manual and benchtop power supply with 115 and 230V power cords.
