Ionode pH at a glance ...

Ionode pH sensors will excel in the most common application types such as swimming pools, water treatment, education, mining, environmental, food, beverage, agriculture and many more. But it's the more challenging and contaminated applications where Ionode sensors have developed a true reputation for precision, long life and exceptional value for money … waste water, soil, meat, electro-plating and chemical processing to name just a few. Underpinning this reliability and performance is a proprietary method of automated glass blowing which provides precise, uniform glass membranes tough enough to withstand the 'drop-test' without sacrificing any speed or accuracy. To complete the value for money equation, Ionode's unique renewable junction in the IJ Series defeats pollutants by protecting the primary junction from contamination and providing an easily renewable secondary junction to extend the life of the sensor.

Ionode also have sensors which excel in environments such as immersion, submersion, high temperature, high pressure, solvents, chemicals and other challenging applications, so don't think that general purpose means average performance as our standard range features the toughest sensor we’ve ever made - the IJ-44.
