Warranty

IJ electrodes have a pro-rata warranty of 12 months from

date of purchase. Any electrode found to be faulty due to

manufacture within this time will be replaced.

Ionode reserves the right to limit or modify product warranty

if it is deemed that the electrode has been used in unsuitable

applications.

IJ electrodes have an expected lifetime of 2-4 years in ideal

samples at room temperature. This may be reduced in

chemically aggressive or abrasive samples and at high

temperatures.
