Automatic Self-Cleaning ISE Ammonia Sensors for Water Quality Monitoring

Description

The NH351 ammonia sensors utilize the ion electrode method to offer compact, user-friendly, and rapid detection capabilities. Perfect for conducting rapid, repetitive, and uninterrupted field assessments, these ammonia sensors operate without the need for reagents, showcasing remarkable stability and minimal maintenance requirements.

Central to their functionality, the NH351 sensors monitor water quality by precisely measuring the total ammonia nitrogen content, encompassing both non-ionic ammonia (NH3) and ammonium ions (NH4+) in water. Ammonia nitrogen serves as a crucial indicator of water quality, as it represents a significant oxygen-consuming pollutant and poses toxicity risks to fish and aquatic life. Elevated levels of ammonia nitrogen can lead to water discoloration, foul odors, and harm to aquatic plants, ultimately threatening the survival of fish and shrimp, with severe impacts on aquaculture productivity.
