Description
DR3900 Laboratory VIS Spectrophotometer with RFID* Technology HACH USA
Optimized for safe processes and consistent, quick and accurate water analysis results
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® and LCK reagents for fast preparation and easy execution. In fact, it automatically recognizes our Hach reagents, so there is no need to enter method numbers
Guided Procedures
The DR3900 simplifies water analysis by with step-by-step guides which take users through testing procedures. This helps ensure consistent and accurate results.
RFID Technology
Featuring state-of-the-art Radio Frequency Identification (RFID) technology* allows for hands-free calibration updates, as it automatically recognizes the lot, expiration and calibration curves associated with each Hach chemistry sample. It also allows for traceability for each measurement.
Claros Enabled
This instrument connects to Claros™, Hach’s innovative Water Intelligence System, enabling you to seamlessly connect and manage instruments, data, and process – anywhere, anytime. The result is greater confidence in your data and improved efficiency in your operations.
Other Key Features
• Optimized for safe processes and accurate results.
• Large color touchscreen display allows easy setup and navigation.
• RFID technology eliminates sample mix-ups and provides better sample traceability.
• Built with 1 ethernet and 3 USB ports, so easily connects to your computer.
• 200+ tests available including EPA compliant parameters such as ammonia, COD, chlorine and more.
Benefits
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.
*RFID technology currently available only in US, and certain other countries. Check the datasheet for country availability.
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.
