DR4900 Spectrophotometer, with Camera, HACH

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 standardise 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 LCK cuvette recognition. The system automatically identifies the correct method for each cuvette, minimising manual errors and ensuring compliance and method traceability.

Technical Innovations That Protect Data Integrity

10-inch High‑Resolution Touchscreen
The large, full‑colour display enables rapid navigation of analytical steps, clear visualisation of spectral data, and fast review of sample information. The modern UI is optimised for multi‑operator labs, reducing training time and minimizing navigation errors.

Integrated Turbidity Diagnostics
Optical monitoring verifies whether sample turbidity may interfere with LCK cuvette 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 standardised 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 Spectrophotometer to deliver reliable, repeatable water quality data while improving analytical efficiency across your laboratory.
