Overview
The DR4900 Laboratory Spectrophotometer streamlines water analysis with enhanced accuracy and modern efficiency. Building on the legacy of the DR3900, the DR4900 is redesigned for today's labs to deliver trusted precision and faster results.

Key Benefits

• Modern user interface: redesigned with large results, clear errors, and easy access to sample ID information.
• Large 10-inch backlit touchscreen: bright screen with simple icons to clearly view readings and search data logs.
• Temperature and turbidity diagnostics: built-in sensors and optics help ensure vial test results are not impacted by sample temperature or turbidity.
• Four simultaneous timers: optimize workflows and avoid missed steps.
• Ten measurements on barcoded vials: barcode reading improves method selection and reduces user error.

Why choose the DR4900?

• Navigate with ease: a large 10-inch color touchscreen provides intuitive menus and easy-to-read results, reducing handling time and training needs.
• Trust your results: enhanced accuracy with built-in diagnostics gives greater confidence and control over measurements.
• Accelerate testing: over 250 pre-programmed Hach methods (including TNTplus vial methods) guide step-by-step analysis for fast, consistent results.
• Seamless data management: connect to the lab network for simple data transfer and secure recordkeeping.

Integration with Hach TNTplus Vial Chemistries
The DR4900 integrates with TNTplus vials for fast, accurate, and safe analysis. Key points include:

• Broad analytical capability: pre-programmed methods for parameters such as ammonia, nitrate, phosphate, total chlorine and more.
• High accuracy & precision: 2D barcode identification and advanced processing reduce errors.
• No reagent blank required: consistent vial quality saves time.
• Lot-specific calibration: batch-matched calibration data reduces variability.
• Traceable & compliant: comprehensive documentation supports compliance and recordkeeping.

What's New
The DR4900 offers a fresher, simpler user experience with new diagnostic features while maintaining Hach’s durable dependability. New built-in turbidity diagnostics and integrated temperature measurements help identify when sample conditions may affect results.
