KZNH3-210 Ammonia Nitrogen Sensor
1. Core Advantages:
• Digital Output
This digital sensor sends data directly through RS‑485 port.
It runs well with MODBUS/RTU communication protocol.
• Automatic Temperature Compensation
A built-in temperature sensor is arranged inside the probe.
It performs real-time temperature compensation during actual measurement.
• Low Maintenance Cost
It adopts replaceable ammonium ion membrane cartridge structure.
This design effectively cuts down overall long-term maintenance expense.
• Easy Installation
It is made with standard 3/4 inch G thread mounting structure.
The layout allows fast and convenient on-site installation.
• Anti‑Interference
It runs at low power consumption with optimized anti-interference circuit.
Built-in pH and potassium ion compensation greatly lowers external signal interference.
316L stainless steel housing provides reliable anti-corrosion performance.

3. Low-Maintenance Design & Long Service Life：
KZNH3-210 uses high-strength ion-selective electrode with optimized anti-fouling membrane.
This structure greatly reduces daily manual maintenance workload.
Only monthly visual check and calibration every one to three months are needed.
Optional automatic cleaning function can lower labor cost by around 80%.
The replaceable electrode membrane lasts 6 to 12 months under regular use.
The stainless steel sensor body can keep working steadily for 3 to 5 years in normal wastewater environment.
It ensures long-term stable operation and minimizes unexpected system downtime.
4. Seamless Integration with Industrial Automation Systems
Built fully for industrial standard connection requirements.
It supports standard RS485 Modbus RTU and 4–20mA analog output.
It can be connected directly with PLC, control cabinets and SCADA platforms in plug-and-play mode.
Matches all mainstream industrial automation systems on the market.
Supports immersion type, pipeline type and side-wall mounting methods.
Suitable for various water quality monitoring sites such as wastewater plants and aquaculture farms.
5. High-Precision Measurement with Full Environmental Compensation
Adopts advanced ISE technology design.
Integrated pH, temperature and potassium ion automatic compensation are all equipped.
KZNH3-210 reaches laboratory level measuring accuracy at ±5% FS or ±0.2 mg/L.
It maintains stable performance even under complicated and changing water quality conditions.
It avoids reading deviation caused by external environmental interference.
Keeps data steady for important application scenarios.
These include wastewater denitrification control, aquaculture water quality management and surface water eutrophication evaluation.
