    GRADUS

    Adrona Gradus is fully integrated and compact pure and ultrapure smart tap water system. It has unique built-in dispensers that provide both ultrapure Grade 1 and pure Grade 2 water.

    The system requires external water tank and comes in 3 main configurations: Gradus Trace, Gradus LT, Gradus Bio.

    It has all-new electronics and software, providing a range of advanced features: large colour touch screen, data logging capability, a wide range of flow control options, drop-by-drop function, the ability to connect multiple remote dispensers, Ethernet and USB interfaces, dispense report preparation, improved accuracy of conductivity and TOC measurements.
