Aluminium analysers provide continuous, automated measurement of aluminium in water across drinking water and municipal treatment applications. Using colorimetric measurement technology, these online analysers track dissolved and total aluminium to support coagulation control and metals removal. The right model depends on your sample type, measuring range, and process complexity.
Which Aluminium Analyzer should I Choose
EZ1001sc, 0.005 - 0.3 mg/L Al: Best for Dissolved Aluminium Monitoring and Coagulation Control
Recommended for drinking water treatment plants that require continuous aluminium monitoring to optimise coagulation, verify filtration performance, and control aluminium residual levels.
The EZ1001sc is a Hach online colorimetric analyser designed for continuous aluminium measurement. Its standard measuring range is 0.005 to 0.3 mg/L Al, with a lower range configuration of 0.005 to 0.15 mg/L Al available for applications requiring sensitive aluminium detection. For samples with higher aluminium concentrations, optional internal dilution extends the measuring range up to 15 mg/L Al.
The EZ1001sc supports aluminium monitoring throughout the treatment process. It helps operators track changes in aluminium concentration, optimise aluminium-based coagulant dosing, verify removal efficiency after filtration, and reduce the risk of aluminium carryover into finished water.
Choose Hach’s EZ1001sc when your process requires continuous aluminium measurement for operational control. It provides real-time data to support stable treatment performance, efficient chemical dosing, and consistent finished water quality.
EZ2701sc, 0.01 - 0.3 mg/L Al(T): Best for Total Aluminium Measurement and Residual Verification
Recommended for drinking water plants that require continuous total aluminium monitoring to verify coagulation efficiency, filtration performance, and final water quality.
The EZ2701sc is a Hach online colorimetric analyser designed for total aluminium measurement. Its standard measuring range is 0.01 to 0.3 mg/L Al(T), with a lower range configuration of 0.01 to 0.15 mg/L Al(T) available for applications requiring increased sensitivity. For samples with higher aluminium concentrations, optional internal dilution extends the measuring range up to 7.5 mg/L Al(T).
The EZ2701sc is well suited for monitoring aluminium removal throughout the drinking water treatment process. It helps verify coagulation and filtration performance by continuously measuring total aluminium, including aluminium forms converted during sample preparation.
Choose Hach’s EZ2701sc when your process requires continuous total aluminium monitoring rather than only dissolved aluminium measurement. It provides reliable process data to confirm aluminium removal, control residual levels, and support consistent finished water quality.
