Storage To prevent damage to the electrode, be sure to observe the following cautions for storage. Store in 40C maximum ambient temperature, and 70% maximum R.H. For maximum possible shelf life do not disturb polythene sleeve until you are ready to use. Store where there are no harmful gases containing sulphur or chlorine.
