Spectrophotometers & Colorimeters

HACH DR 6000™ UV VIS Spectrophotometer

The HACH DR6000™ UV-Vis Spectrophotometer, one of the industry’s most advanced laboratory instruments for water analysis. With high-speed wavelength scanning across the UV and visible spectrum and more than 250 pre-programmed methods, it covers the most common testing needs with precision and efficiency.

Optional accessories, such as a carousel sample changer for sequential measurements and a sipper module for controlled sample delivery, support high-volume and high-accuracy testing. When paired with TNTplus® reagent vials, the DR6000 guides users step by step through procedures, averages 10 readings, and eliminates outliers, ensuring reliable results even with scratched or flawed glassware.

The RFID technology automatically updates calibration factors, tracks reagent expiration, and prevents lot-to-lot variation errors, while integrated QA software streamlines scheduling, documentation, and interpretation of results. The DR6000 combines innovation, accuracy, and ease of use—meeting all your water testing needs in a single spectrophotometer.
