Vernier's Ammonium Ion-Selective Electrode (ISE) can be used to measure the concentration of ammonium (NH4+) in aqueous samples.

Use the Vernier 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+.

Vernier's 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.

As this product has a finite shelf life we import it as required, allow 4 to 6 weeks for delivery from the date of your order.

Important: Ion-Selective Electrodes require good chemical technique and careful calibration to obtain accurate results; they are not recommended for junior high school students.
