Vernier™ Go Direct™ Potassium Ion-Selective Electrode

Vernier™ Go Direct™ Potassium Ion-Selective Electrode can be used to measure the concentration of potassium ions in aqueous solutions.

Supplier:  Vernier™ GDXK

Catalog No. S39715

Description

• 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.
