Technical Specifications

The NH4-100 delivers precise ammonium measurements from 0.1 to 18,000 mg/L with automatic temperature compensation via the integrated PT1000 sensor. The ion-selective membrane provides exceptional selectivity for ammonium ions, crucial for accurate nitrogen cycle monitoring.

The fast response time of less than 30 seconds enables real-time process control and rapid detection of ammonium spikes.

Understanding Ammonium Monitoring

Ammonium monitoring is crucial for:

• Wastewater Treatment: Optimizing biological nitrogen removal processes
• Aquaculture: Preventing toxic ammonium accumulation that harms fish
• Environmental Protection: Tracking nitrogen pollution in water bodies
• Regulatory Compliance: Meeting discharge limits for total nitrogen
• Process Optimization: Controlling aeration and chemical dosing costs

Connectivity and Integration

With its RS485 Modbus RTU interface, the NH4-100 seamlessly integrates into modern SCADA systems and IoT networks. The 4-20mA current output option ensures compatibility with traditional industrial controllers and data acquisition systems.
