Ammonium ISE for the HI-9829
The HI-7609829-10 is an ammonium ISE sensor with o-ring, to be used with the HI-9829 and HI-98290 series of multi-parameter meters.
A choice of three ion selective electrodes (ISE) are available for constant reporting of common surface water contaminants. Choose from nitrate, ammonium and chloride ISEs. Each ISE is a combination electrode incorporating an extremely constant reference spiral; all potentionmetric probes feature a double junction and solid gel reference design. The HI-9829 displays measurements of ion activity as ppm ammonium-nitrogen, ppm chloride, and ppm nitrate-nitrogen.
The HI-7609829-10 utilises a polymeric membrane constructed in a PVC head. This sensor is used in the pH sensor socket of the probe.
IP68 - Dust-tight and protected against the effects of continuous immersion in water beyond 1m.
