The directION combination ion selective electrode has a solid state PVC polymer membrane with an integral driTEK reference electrode. The electrode is designed for measuring Water Hardness in aqueous solutions and is suitable for use in the field in the laboratory and in on line analyzers.

Note this electrode is a Calcium sensor and gives a guide to  Water Hardness since the majority of Water Hardness is due to Calcium rather than Magnesium salts. This electrode will therefore not be suitable for the determination of Magnesium concentration or WAter Hardness caused predominantly by Magnesium salts.
