Industrial Application:
The DR900 is critical for municipal wastewater treatment facilities and industrial effluent discharge monitoring. By enabling immediate on-site quantification of nutrient loads (Ammonia Nitrogen, Total Nitrogen, Total Phosphorus), operators can adjust aeration and chemical dosing in real-time. This prevents eutrophication in receiving waters and ensures strict adherence to environmental discharge permits.
Procurement and Integration:
Technical Compatibility is guaranteed with standard HACH reagent sets and sample cells (1-inch round, 16 mm, 1 cm). We ensure minimal Lead Time for this essential analytical equipment, providing facilities with reliable, factory-calibrated instrumentation ready for immediate deployment.
