Features

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.
