The IJ SERIES ... looks different ... is different.
- You'll find an IJ sensor to suit most applications and parameters including pH, REDOX and ion specific determinations such as fluoride, chloride, iodide, bromide, cyanide and others.
- IJ are unequalled in water, food, wine, dairy, contaminated samples, industrial and mining applications and the harshest of laboratory environments.
- IJ are tough ... try the drop test on any other sensor !
- IJ have unique junction mechanics which protect the primary reference from the contamination associated with traditional gel electrodes whilst providing the low maintenance and long life of a refillable sensor.
- The intermediate junction is easily and quickly cleaned and electrolyte renewed to defeat contamination.
- Users can optimise the electrolyte to suit their sample.
- Hardened spear membrane makes it ideal for direct penetration into cheese, cured meats and much more.
- IJ are perfect for non-aqueous measurements and titrations.
- IJ are a safer and more simple choice for replacing calomel sensors.
- IJ have no hazardous mercury and fit directly into an Eppendorf tube for life science and pharmaceutical applications.
- Highly resistant to clogging from fats, proteins and solids.
- Ground glass annular junction is super-sensitive and time proven in difficult samples.
- Poypropylene or Kynar construction.

Let us tell you how the IJ Series was developed and just why it's so good ...
Many years ago we learned that users of laboratory, field and industrial sensors really needed a solution to those annoying problems of clogging, failures, breakages, hydration issues, calibration problems etc. Our scientists and engineers decided that they could develop a sensor that fixed those problems, would work in any sample and would last ... 'forever' ... so they did !
Our knowledge of chemistry lead us to develop special intermediate junction technology which resulted in far less contamination and incredible reliability. We then automated our laboratory and 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. We wrapped it all up in a tough and flexible body and called it 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.
The IJ 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.
