Product Description


The NavGo Direct Ammonium Ion-Selective Electrode (ISE) can be used to measure the concentration of ammonium (NH4+) in aqueous samples. It connects via Bluetooth® wireless technology or wired via USB to your device.



Use the NavGo Direct Ammonium Ion-Selective Electrode to wirelessly 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 versatile BNC connector allows users to easily replace the electrode when it expires or becomes damaged. You need only replace the electrode and not the entire sensor—lowering your overall equipment costs.

Free WIFI Communication and Analysis Software for iOS, PC, Android.
