Ionode pH at a glance ...

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

Ionode have general purpose sensors which excel in the most challenging environments such as immersion, submersion, high temperature, high pressure, solvent and chemical resistance and other challenging environments, but don't be fooled into thinking that general purpose means average performance as our standard range features the toughest sensor we’ve ever made - the IJ-44.
