IONODE's knowledge of chemistry lead them to develop special intermediate junction technology which resulted in far less contamination and incredible reliability. They then learned how to perfectly reproduce glass membranes which are super-tough and super-fast and then developed the annular ground-glass junction to give fantastic sensitivity. All wrapped it all up in a tough and flexible body and called the IJ. (short for intermediate junction) The benchmark in sensor versatility, reliability and performance was born. No need now for different sensors for different applications ... The IJ sets the standard and does them all

The ionode IJ44A specification:

The IJ Koala Series are used in some of the most demanding applications imaginable and are the preferred choice of scientific communities in dozens of industries. Ionode products are relied upon by the Australian & New Zealand Wine Industry, Master Winemakers of Australia, MLA (Meat & Livestock Association of Australia), DIAA (Dairy Industry Association of Australia), Universities and educational institutions, regional councils, governments, water industry operators, agricultural & mining companies and countless more.
