Details

The Go Direct Potassium Ion-Selective Electrode BNC is a BNC-terminated electrode used to measure the concentration of potassium (K⁺) ions in aqueous samples. Requires a Go Direct^® Ion-Selective Electrode Amplifier. The Go Direct Potassium Ion-Selective Electrode BNC 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.
