Adrona Gradus EDI is a fully integrated and compact pure and ultrapure smart water system. It features unique built-in dispensers that provide both ultrapure Grade 1 and pure Grade 2 water.
Gradus EDI systems are designed for laboratories with high daily consumption of pure and ultrapure water. This allows a significant reduction in the operating costs of the water treatment system, as the EDI module does not need to be replaced.
The system requires an external water tank and comes in 3 main configurations: Gradus EDI Trace, Gradus EDI LT, Gradus EDI Bio.
It features all-new electronics and software, providing a range of advanced features: large color 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.
