DR3900 SPECTROPHOTOMETER FOR WATER ANALYSIS HACH
This photometer system is designed to deliver accurate results by supporting the operator with each step he is doing:
• Sample preparation: reduced handling steps, precise dosing
• Sample analysis: automatic test recognition, expiration date check etc.
• documentation of results: versatile data management, control cards
With your daily routine of water analysis in mind the DR3900 spectrophotometer is optimised for safe processes and meaningful reports. Control-parameters like Ammonium, COD, Phosphate, Nitrogen and many others are easy to perform. The handling of tests and photometer 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.
