The Hach EZ1016 is a high-precision online analyzer designed for the continuous and automated monitoring of dissolved Iron (Fe II) concentrations in water. By utilizing professional-grade colorimetric analysis, it provides critical real-time data for drinking water treatment, groundwater monitoring, and industrial process control where iron levels must be strictly managed to prevent scaling, staining, or product contamination.
The EZ1016 (No. EZ1016.9700140T) is a specialized volumetric analyzer that automates the 1,10-phenanthroline method. In this process, orange-red complexes are formed with iron in the ferrous state (Fe II) in a pH-buffered environment. The intensity of the color is measured by a high-precision integrated photometer, providing a direct and accurate reading of the iron concentration. This specific model is configured with a 0 - 1 mg/L measuring range, making it ideal for high-sensitivity applications. The analyzer is equipped with a smart controller that manages automatic priming, validation, and cleaning cycles, which significantly reduces the risk of sensor fouling. Housed in a robust IP44-rated industrial cabinet, it features an integrated panel PC with a touchscreen for intuitive data visualization and configuration. Its modular design is also multi-stream capable, allowing for the sequential monitoring of up to 8 separate sample lines with a single instrument.
Advantages
- High Sensitivity and Precision: The phenanthroline colorimetric method offers superior accuracy for trace-level iron detection compared to manual test kits or broader-range sensors.
- Automated Operational Maintenance: Programmable self-cleaning and automatic calibration routines ensure the photometer remains clear and accurate with minimal human intervention.
- Cost-Effective Multi-Stream Sampling: A single analyzer can be configured to monitor multiple points in a process (up to 8 streams), reducing the total cost per sampling point.
- Industrial-Grade Reliability: The physical separation of the wet-chemical and electronic compartments ensures long-term durability and safety in harsh plant environments.
- Real-Time Trend Analysis: The industrial panel PC provides live graphing and data logging, enabling operators to respond quickly to process fluctuations.
- Flexible Range Adjustment: While configured for 0 - 1 mg/L, the internal dispenser system can facilitate dilution to adapt the analyzer to higher concentration ranges if required.
Instructions for use
The EZ1016 is designed for fully autonomous online operation once integrated into the water loop. Preparation: Ensure a constant supply of demineralized water for automated rinsing. Connect the sample inlet line (maintaining a flow rate of 100 - 300 mL/min) and install the required reagents: 1,10-phenanthroline indicator and the specific acetate buffer solution. Note: Configure the measurement frequency and alarm setpoints via the touchscreen interface. The analyzer will automatically draw a sample, stabilize the pH, develop the color complex, and record the measurement. Data is transmitted to the plant SCADA system via 4-20 mA outputs or optional Modbus TCP/IP. Routine maintenance is minimal, generally involving reagent replenishment and a 6-month inspection of the peristaltic pump tubing.
