Ammonium Ion-Selective Electrode - Probe
Use the Ammonium ISE to measure levels of ammonium ions introduced from fertilizers. It can also indicate aqueous ammonia levels if sample solutions are acidified to convert NH3 to NH4+. The Ammonium ISE has a combination-style, non-refillable, gel-filled electrode. Like all other PVC ISE membranes, the membrane on the ISE has a limited life expectancy. However, the replaceable module of ISE allows you to simply discard the used membrane module, and replace it with a new one. Probe must be used with a Vernier interface (i.e. LabQuest and LabQuest Mini) or a computer with Vernier software. Click link for Vernier software tutorial
