Description
Description
Overview
GAOTek’s ammonium ion-selective electrode (ISE) offers reliable detection of NH₄⁺ in freshwater using a liquid-membrane design and gel-filled, double-junction reference. Built with a durable PEI body and color-coded for easy replacement. Designed for integration into HI9829 multiparameter probes, it ensures robust field performance across a wide concentration range. Ideal for environmental, wastewater, and aquaculture monitoring.
Features
- Measures free ammonium-nitrogen (NH₄⁺-N) in freshwater with precision.
- Liquid polymeric PVC membrane with specific ammonium ionophore.
- Gel-filled, double-junction Ag/AgCl reference for stable readings.
- Robust PEI sensor body, chemically resistant and field-durable.
- Color-coded connector ensures easy, error-free installation.
Applications
- Monitoring ammonium levels in environmental water bodies.
- Wastewater treatment process control and discharge compliance.
- Aquaculture water quality tracking for fish/prawn health.
- Integration into multiparameter water quality analyzers.
