$45.46
$74.55
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.
