The DR3900 is designed to deliver accurate results quickly with Hach’s innovative TNTplus and LCK reagents, which are optimised around:

  • Sample preparation: reduced handling steps, precise dosing
  • Sample analysis: automatic test recognition, expiration date check, etc.
  • Utilisation of the new Truecal software to eliminate lot to lot variation
  • Documentation of results: versatile data management


The DR3900 is a benchtop visible spectrum (320 – 1100 nm), split beam spectrophotometer with over 220 pre-programmed methods optimised for laboratory water analysis. With your daily routine of water analysis in mind, the DR3900 spectrophotometer is optimised for safe processes and accurate results. Control-parameters like Ammonium, COD, Phosphate, Nitrate and many others are easy to perform. The handling of tests and spectrophotometer is well designed to avoid any errors in your water analysis.

This instrument connects to Claros, Hach’s innovative Water Intelligence System, enabling you to seamlessly connect and manage instruments, data, and process – anywhere, anytime. The result is greater confidence in your data and improved efficiency in your operations. To unlock the full potential of Claros, insist on Claros Enabled instruments.
