Total Ammonia Nitrogen Sensor - for Workplace - BOQU
Product Overview
Note: the detailed text you provided describes BOQU’s BH-485-NO3-N digital online nitrate nitrogen sensor. I summarize its key points below in the five requested categories.
Product Features
1) Product overview
Product Value
- Integrated digital online nitrate nitrogen sensor (BH-485-NO3-N) using an ion-selective electrode method to measure nitrate nitrogen (NO3–N).
Product Advantages
- Built-in electrodes for nitrate plus optional potassium (and chloride), pH and temperature for mutual compensation.
Application Scenarios
- Compact, rugged probe design with RS485 Modbus communication and IP68 protection for direct basin installation.
2) Product features
- Direct, continuous nitrate measurement without reagents or sample conditioning.
- Multi-parameter sensing: NO3–N (0.1–1000 mg/L), optional K+ (0.5–1000 mg/L), pH (5–10) and temperature (0–40 °C); resolutions and response time ≤2 minutes.
- Standard RS485 Modbus RTU output, DC12V power, reverse polarity protection and standard 10 m cable (extendable to 100 m).
- Robust ion-selective membranes to reduce maintenance; installed on basin rim—no sample pump or container required.
3) Product value
- Low operating cost: reagent-free measurement and reduced sampling/maintenance effort.
- Enables better process control (e.g., aeration optimization) leading to energy savings and improved treatment efficiency.
- Continuous online data supports predictive maintenance and trend-based decision making.
- Multi-parameter compensation improves measurement reliability in complex matrices.
4) Product advantages
- High precision and stability: NO3–N accuracy ±5% or ±0.2 mg/L; fast response and low detection limits (~0.2 mg/L).
- Integrated compensation (K+, pH, temperature) reduces cross-sensitivity and improves result accuracy.
- Rugged, easy-to-install design (IP68) suitable for direct basin mounting; minimal auxiliary equipment needed.
- Digital RS485 interface simplifies integration with control systems and remote monitoring.
5) Application scenarios
- Wastewater treatment plants for continuous nitrate monitoring and aeration/process control.
- Industrial effluent monitoring where online nitrate measurement is required.
- Environmental and basin monitoring (surface water or process basins) with direct in-situ installation.
- Aquaculture or other water-quality management applications that benefit from reagent-free, continuous nitrate data.
