EZ Series Analysers

EZ Series Analysers
Hach EZ Series Online Analysers
The EZ sc and EZ Series Online Analysers from Hach provide continuous, 24/7 monitoring of critical water parameters on a single, flexible platform. Built for drinking water, wastewater, and industrial process applications, these analysers measure everything from aluminium, ammonia, and hardness to nitrate, phosphate, and silica, as well as total nitrogen, total phosphorus, and beyond, so you can keep control of your process around the clock.

With a common user interface across every model, the EZ Series simplifies operation, shortens training, and streamlines maintenance, giving your team one consistent way to manage water analysis.

Broad Parameter Coverage Across the EZ Series Family
The EZ Series covers a wide range of parameters across four practical categories:
• Nutrients: ammonia, nitrate, phosphate, total nitrogen, and total phosphorus for nutrient removal, compliance monitoring, and process optimisation.
• Metals: aluminium, iron, manganese, copper, zinc, chromium, nickel, and arsenic for coagulation control, drinking water quality, and industrial process monitoring.
• Inorganics: chloride, fluoride, silica, sulphate, cyanide, alkalinity, and hardness for water treatment, equipment protection, and regulatory compliance.
• Specialty and Other: ATP, toxicity, volatile fatty acids, and colour.

Dedicated online analysers are available for each parameter, allowing you to select the solution that best fits your application while maintaining a common platform, user experience, and maintenance approach across your monitoring network.

One Common Platform, Simpler Operation
Every EZ Series analyser shares a common user interface on an industrial panel PC, so once your team learns one model, they can operate them all. That consistency reduces training requirements and helps operators move confidently between measurement points.
Additional platform benefits include:
• Common hardware and shared spare parts across many EZ Series analysers, helping simplify inventory management.
• Flexible analog and digital communication options for easy integration into existing control systems.
• Programmable analysis intervals to help optimise reagent consumption.
• Guided workflows and alerts that support routine maintenance.
• Worldwide Hach service and support to help maximise uptime and protect your investment.
