Go Direct® Potassium Ion-Selective Electrode
- Order number: GDX-K
- Supplier Name: Vernier Science Education
- Supplier Number: GDX-K
- Warranty(Years): 5
Use the Go Direct Potassium Ion-Selective Electrode to wirelessly measure levels of potassium ions.
The versatile BNC connector allows students 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.
The Go Direct Potassium Ion-Selective Electrode 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.
