Description
The Inline Ammonia Nitrogen Sensor is a cutting-edge digital sensor designed for precise measurement of ammonia nitrogen concentrations in various water environments.

This sensor is only for use with:
Sper Scientific 870001 Multi-Parameter Water Quality Analyzer
Utilizing advanced ion selective electrode technology, this sensor delivers reliable and accurate readings essential for effective water quality management. Its advanced technology and precision sensors allow for precise and consistent readings, ensuring the quality and integrity of experimental data.
-
Direct Measurement: The sensor employs an ammonium ion selective electrode that directly detects ammonium ions, ensuring accurate determination of ammonia nitrogen levels.
-
Stability: A pH electrode serves as a reference, enhancing the stability of measurements and ensuring consistent performance.
-
Interference Compensation: The sensor includes potassium ion compensation to mitigate interference from potassium ions, providing more reliable readings in varying water conditions.
-
Integrated Design: This comprehensive sensor probe integrates an ammonium ion selective electrode, an optional potassium ion electrode, a pH electrode, and a temperature electrode, allowing for multi-parameter measurements.
- Advanced Technology: Its advanced sensors allow for precise and consistent readings, ensuring the quality and integrity of experimental data.
- Versatile Applications: Ideal for use in sewage treatment plants, nitrification processes, aeration tanks and industrial water systems, as well as in scientific research and river water.
Ordering Notes:
1. All Sper Inline Water Quality Meters and Sensors are sold separately - one of each is required for a complete system.
