Online Turbidimeters for Water Quality Monitoring
Turbidity Analysers
Clarity, Without the Complexity.
See the Difference That Turbidity Makes.
Across water quality analysis turbidity monitoring that is accurate, compliant, and easy to maintain. Implementing turbidity analysers offers several advantages, particularly in industries where liquid quality is paramount Operators need turbidity readings they can act on, not chase after and plants need instruments that detect changes quickly, stand up to challenging environments, and deliver reliable data for regulatory reporting. Hach turbidity analysers help with those very concerns.
With continuous, accurate turbidity monitoring, you can meet compliance requirements, respond faster to changes, and maintain confidence that your data reflects true process conditions.

TU5300sc/TU5400sc
Laser-Focused Accuracy for Today’s Compliance Needs
Built on Hach’s innovative 360° x 90° optical design, the TU5 Series sets a new standard for turbidity monitoring. These analysers “see more of your sample than any other turbidimeter,” providing unmatched low-level precision and fast response for drinking water compliance and beyond.
Key Benefits:
- Detect turbidity changes almost instantly with reduced sample volume
- Ensure compliance with EPA Approved Method 10258
- Reduce maintenance with 98% less sample surface area to clean and sealed vials for calibration
- Eliminate uncertainty between lab and online measurements with identical optics
- Optional smart add-ons: flow sensor, automatic cleaning module, system health checks
Surface Scatter 7sc
When water conditions are extreme, you need an analyser that holds steady.
The Surface Scatter 7sc High Range Turbidimeter is the original non-contact turbidity solution, designed to measure up to 9,999 NTU without sacrificing accuracy.
Why it Matters:
- Handles high solids without clogging or constant cleaning
