Description
Bringing Effortless Accuracy to Your Lab
Built on the trusted legacy of the DR3900, the DR4900 Spectrophotometer increases analytical reliability and strengthens your laboratory’s operational performance. Engineered for routine and high‑throughput water analysis, the instrument combines stable optics, automated verification functions, and streamlined workflows to deliver consistent, traceable results across a wide range of parameters.
Accurate, reproducible data is fundamental for laboratory oversight. The DR4900 reduces sources of analytical variability by integrating diagnostic controls, guided workflows, and an interface designed to standardize testing steps. The result is fewer repeat analyses, reduced operator‑dependent variation, and better confidence in day‑to‑day results.
The DR4900 Lab Spectrophotometer with a built-in workflow camera features barcode-based TNTplus vial recognition. The system automatically identifies the correct method for each vial, minimizing manual errors and ensuring compliance and method traceability.
Technical Innovations That Protect Data Integrity
10-inch High‑Resolution Touchscreen
The large, full‑color display enables rapid navigation of analytical steps, clear visualization of spectral data, and fast review of sample information. The modern UI is optimized for multi‑operator labs, reducing training time and minimizing navigation errors.
Integrated Turbidity Diagnostics
Optical monitoring verifies whether sample turbidity may interfere with TNTplus vial measurements. The system alerts the operator when filtration or additional sample preparation is recommended, helping maintain result accuracy in samples with suspended solids.
Temperature Monitoring for Vial Tests
An integrated temperature sensor evaluates vial temperature prior to measurement. This helps ensure that exothermic reactions or insufficient equilibration times do not impact analytical output, particularly important for temperature‑sensitive colorimetric methods.
With more than 250 pre‑programmed Hach methods, including a broad range of regulatory‑relevant parameters, the DR4900 supports standardized workflows and consistent method execution. Its robust optical design and built‑in diagnostics help maintain instrument performance over time, giving you greater oversight and control over daily testing operations.
Trust the DR4900 Lab Spectrophotometerto deliver reliable, repeatable water quality data while improving analytical efficiency across your laboratory.
Proven Technology, Modern Interface
The DR4900 Spectrophotometer maintains the trusted core of the DR3900, now enhanced with a 10” screen and modern user interface that helps reduce training time and speed up routine workflows. It’s the familiar performance lab professionals trust—elevated for modern needs.
Ensuring Reliable Results with Unrivaled Diagnostic Features
Temperature and turbidity diagnostics help prevent common testing errors -- reducing rework and ensuring consistent accuracy. When using Hach TNTplus vial chemistries, the DR4900 automatically checks the temperature and turbidity of your test, providing you with alerts when out of range, giving you the confidence you need in every measurement.
Complete Confidence - From Start to Finish
DR4900 users benefit from end-to-end expertise across instruments, chemistries, and service. So you get faster resolutions, deeper insights, and consistent results from a single partner.
DR4900 options to fit your workflow
Two versions of the DR4900 are available: one without an external camera (LPV451.99.00021) or with an external camera (LPV451.99.00121) to enable Smart Workflow features including Certificate of Analysis QR code scanning and Sample ID Text Recognition.
• Without Camera (LPV451.99.00021)
Delivers the full DR4900 analytical performance and error prevention features for routine lab workflows
• With Camera (LPV451.99.00121)
Includes all DR4900 performance features plus an external camera that enables Smart Workflow capabilities such as Certificate of Analysis QR code scanning and Sample ID Text Recognition - reducing manual data entry and supporting documentation tracking directly at the instrument.
