The EDT direction Sodium ISE is a glass based 12mm bodied electrode which is sensitive to Sodium levels down to ppb levels.
This ISE operates in exactly the same way as a traditional combination pH electrode except the bulb glass is ultra-sensitive to changes in Sodium concentration.
An important consideration is that the pH of standards and samples need to be in the range pH9-12. If low level Sodium work is to be performed the pH should be 12 as the glass bulb is still sensitive to Hydrogen Ions which should be minimised.
Each EDT directION Combination ISE has a 1 metre cable and a BNC connector (other connectors available on request) allowing use on all types of pH/ION meter including laboratory bench and research models. For direct concentration reading and absolute simplicity the EDT DR359TX pH/ION meter is the perfect instrument for these ISEs.
