Informations sur le produit "ISE Ammonium Replacement Module"
This module replaces the electrode membrane. Simply unscrew the old one and screw on the new one. The membrane of an Ammonium ISE electrode has a limited life span of one to two years, regardless of frequency of use. Do not order it until you need it, as it will age even when not in use.

Ammonium Ion-Selective Electrode

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.
Note: We recommend that you do not purchase ISE replacement modules too far in advance of their expected time of use as degradation occurs while they are stored on the shelf.
Important: Ion-Selective Electrodes require good chemical technique and careful calibration to obtain accurate results; they are not recommended for middle school or elementary students.
