IJ Series Intermediate Junction Electrodes
Setting the benchmark in super-long life, versatility and value for money since 1972, the flagship of the Ionode Lab sensor range is the renowned IJ Series.
Built to exacting standards and available in pH, ISE, ORP and Reference, the IJ Series benefits are many … A removable sleeve and renewable junction for longer life and easy cleaning, an isolated secondary reference to effectively defeat contamination, an annular ground-glass junction to provide fast response times and resistance to clogging, selectable electrolyte and an optional toughened glass spear membrane for direct penetration. An exceptional choice in virtually any sample, the IJ Series is unequalled in food, wine, dairy, contaminated waste samples, industrial, mining, petro-chemical, electro plating and countless more. The IJ Series also features models with solvent resistant bodies and high temperature housings for the most demanding of environments.
- Replaceable electrolyte
- Removable sleeve
- Available for pH, ISE & ORP
- Polypropylene body
Way back In 1972, History of the Intermediate Junction
Back in 1972, Ionode's R&D Chemists and Engineers set out to develop a sensor that would solve the common problems of contamination and clogging etc. but still be tough, fast and super reliable. Working together, they decided it was possible and they set to work on what would become the IJ Series … a sensor that would defeat contamination, work in any sample and have a lifetime far in excess of other single or double junction sensors. The benchmark in sensor versatility, reliability and performance was then born in the IJ Series. Featuring a renewable intermediate junction for easy cleaning, Ionode's proprietary glass formulae and a tough yet flexible body, the IJ Series quickly earned it's reputation for having the longest life in the industry and being the best value sensor available.
More Junctions, Less Contamination
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.Removable Sleeve
IJ electrodes have a removable sleeve to make cleaning quick and easy.
