EZ5005 Hach Total Hardness & Total/Free Alkalinity Analyzer

The EZ5005 (No. EZ5005) is a sophisticated volumetric titrator that automates complex laboratory procedures for continuous online monitoring. It employs acid-base titration to determine alkalinity levels and Calgamite EDTA titration with an integrated LED dipping probe to measure total hardness. This dual-method approach allows the system to deliver precise results for three distinct parameters in a single cycle. The analyzer features a smart controller that manages automatic validation, priming, and cleaning cycles, ensuring maximum uptime with minimal manual intervention. Its modular design allows for customization, including multi-stream analysis for up to 8 separate sample lines. The wet-chemical and electronic sections are strictly separated for safety, housed in an ergonomic cabinet with a transparent door for easy visual inspection of the titration process.

Advantages

• Multi-Parameter Efficiency: Monitors Total Hardness, Total Alkalinity, and Free Alkalinity in one unit, reducing the need for multiple specialized analyzers.
• High Precision Titration: Utilizes a high-precision dispenser and robust peristaltic pumps to ensure accuracy better than 2% of the full-scale range.
• Automated Maintenance: Integrated self-cleaning and validation features minimize operator intervention and prevent cross-contamination between samples.
• Modular Flexibility: Can be configured for multiple sample streams (1, 2, 4, or 8), significantly lowering the cost per sampling point.
• Industrial Reliability: Features an integrated industrial panel PC and a robust IP44-rated cabinet designed for demanding environmental and industrial sites.
• Extended Range Options: The standard measuring range can be customized or extended via internal dispenser dilution to match specific application needs.
