EZ4003 Hach Total Hardness Analyzer

The EZ4003 (No. EZ4003) is a high-performance volumetric titrator engineered to replace manual laboratory testing with autonomous online monitoring. It utilizes the EDTA titration method combined with a Calgamite-based colorimetric indicator to determine Total Hardness with exceptional accuracy. The system features an integrated optical dipping probe that detects the exact color change at the titration endpoint, eliminating human error. Designed for industrial reliability, the analyzer includes a smart controller that manages automatic cleaning, priming, and validation cycles. Its modular architecture supports multi-stream analysis, allowing a single unit to monitor up to 8 separate sample lines. The device is housed in a robust IP44 cabinet, providing a clear physical separation between the wet-chemical components and the high-performance industrial panel PC interface.

Advantages

• High Precision & Repeatability: Advanced volumetric titration technology ensures accuracy better than 2% of the full-scale range, meeting stringent quality standards.
• Automated Maintenance: Programmable self-cleaning and automatic validation features maintain sensor health and prevent chemical scaling within the system.
• Cost-Effective Multi-Stream Monitoring: Supports sequential sampling from up to 8 streams, significantly reducing the capital investment per measurement point.
• User-Friendly Interface: The industrial panel PC features a large touchscreen for intuitive navigation, data visualization, and configuration.
• Reliable End-Point Detection: The integrated LED optical probe ensures consistent results regardless of sample turbidity or lighting conditions.
• Flexible Range Management: The measuring range can be tailored to specific application requirements through internal dispenser-controlled dilution.
